Note: CPU usage is high in PepperFlash version, even when isn't on Full Screen.

Comment 8 by Deleted ...@, Aug 10 2012

When I go to the tools section or try the plug in fix with Peperflash, it will not let me see the three plug ins so I can not disable... everything works fine with IE, which I hate using as it is so slow....please fix this issue. XXXXX

Comment 9 by, Aug 10 2012

Google chrome constantly crashes with utube, won't play videos. Watching ustream live or pre-recorded freezes up and stops and starts like hickups. Doesn't matter is screen is normal or full screen: same problem. Google chrome has a constant problem which they don't fix. So guess we will all have to go back to IE or Firefox! They are forcing us to make this decision as no fixes for their problems. It's a shame as their speed was great when it worked! But I can't put up with any more google chrome has stopped responding and having to totally shut down my computer and restart! GOOGLE Chrome People wise up and fix your problems or you will become extinct like other companies who don't listen to their clients who use their system. Using Windows XP.

Same problem with choppy video on full screen mode in Chrome.  Using Windows XP and IE and Firefox work perfectly.  Goolge used to be so great at putting out good products.  They've gone the way of the mega company.  Chrome is starting to suck and it's days on my 9 computers are numbered.  It's sad when even IE looks good.

yep, disabling pepflashplayer.dll as prescribed earlier in this discussion worked for me too.
Here is the link
Thank you folks!

Comment 15 by, Aug 16 2012

Same problem. Disabling pepflashplayer.dll works, but it is only a temporary fix for me. Every time I start a new session, it's enabled, and I have to go back into plugins and disable it again. It's getting really annoying, I may go back to Firefox if this isn't resolved soon.

Same issue, disabling PPAPI plugin resolves problem. For those less saavy, Adobe recommends:  
Navigate to "about:plugins" in the Chrome address bar
Click the Details link in the upper right part of the page to expand all items
Locate the "Shockwave Flash" entries (there will be 2 or 3 of these)
Click "Disable" for the PPAPI copy (most likely the first one listed), which has a version number of
Restart Chrome for good measure and try again

Comment 19 by Deleted ...@, Aug 17 2012

I tried Comment 18's suggestion and it worked!  Thanks.

Comment 20 by, Aug 19 2012

@Comment 18. That is what I've been doing, and it's fine for the current session, but every time I start my computer and open Chrome, I have to do it redo it, because PPAPI has been enabled again. Is this only happening to me, and does anyone have a way to make the fix permanent?

Comment 21 by, Aug 19 2012

If I disable the pepflashplayer.dll, then I get a message that I need to enable AdobeFlash when in Chrome watching a video, Is there another plugin I can use to watch videos in Chrome? Or do I have something really screwed up?

Comment 22 by, Aug 20 2012

@Comment 21. You should have 2 or 3 plugins. You need to disable only PepperFlash. See if this video help you.

Is this the same as  Issue 141796 ?

On WinXP, I've noticed Youtube's controls are blurry in Pepper Flash (see attached comparison screenshots).  Maybe the scaling's a bit off, hence the high CPU?

I'm still seeing slow/jerky performance with the PPAPI "Pepper" Flash plugin on Windows 7, and have many reports from users complaining of the Flash sluggishness compared to the NPAPI version. (Also  issue 142102 )

Comment 35 by, Sep 8 2012

I've also started to face this issue recently on my WINXP machine - YouTube videos run poorly in full-screen with PPAPI Flash. Issue persists as of Chrome 21.0.1180.89. Obvious (temporary) workaround is to disable the PPAPI version of the Flash plugin and to enable the NPAPI version.

Comment 36 by, Sep 8 2012

This is really annoying and makes me think about not using chrome anymore :(
With PPAPI flash from google stage3d(all new flash games for example Farmville 2 etc.) hardware acceleration is not working at all on windowsXP and i just want to use proper flash player from adobe. I dont understand why after each update PPAPI Flash is turned on again. I dont want to use it because it is not working for me(no hardware acceleration of stage3d)

Comment 38 by, Sep 10 2012

@37 Unfortunately we needed to disable GPU acceleration due to  issue 130505 . Please follow  issue 136447  to follow the progress of turning it back on.

Comment 39 by, Sep 11 2012

I don't know if it helps, but Chrome 23 (dev) works fine with PepperFlash for me. I believe that finally this problem it'll be fixed. Thanks Google Chrome team.

Comment 40 by, Sep 23 2012

Anyone know how to permanently disable PPAPI flash? I can disable it through chrome://plugins but next time I open chrome it's back again. I have users complaining about flash crashes/hangs and I think the Adobe version will fix this but I need to default to the Adobe version.

MatthewKropchuk: That should be fixed soon, see  issue 150596 .

Comment 42 by, Sep 23 2012

Ok. Will we have to wait for Chrome 23 Stable?

Comment 43 by, Sep 26 2012

I was wrong... The performance in Normal flash is much better than pepperflash.

Comment 44 by, Sep 26 2012

What is taking so long to fix this problem?

Comment 45 by Deleted ...@, Sep 27 2012

Disabling pepperflash and using the npapi flash worked fine, but now the npapi flash no longer appears in the plug-in panel, only the pepper flash version. Please either fix or bring back the option to use the other flash!

Comment 46 by, Sep 28 2012

@Comment 45 it's necessary to install Flash, follow the link:

Chrome team, PepperFlash doesn't work fine.

Comment 47 by, Sep 30 2012

Hi,I am having a similar problem.  Sometimes all sites/Flash video sites work but more frequently now I get choppy flash video playback in both standard and full screen formats in chrome on youtube and news sites using Flash. When it happens, I tested the exact url in firefox and ie without any issue.  

The happened before and I noticed it only happened when "Media Monkey" was it's not open and the video is still having problems.

How come this is still an  issue 2  months later? Using Firefox 90% of the time now.

Comment 49 by, Oct 3 2012

Agreed. And it's a case of multiple instances of flash running when it
should just be one. Can't be that hard to solve!

Comment 50 by, Oct 3 2012

Google gives a S%%T less about us people having trouble with flash playes and google chrome not working with windows XP. It's pretty obvious or they would fix the problem, we are only peons to them!!!!!!!!!!!!!!!!!!!!!!!!!!!

Comment 51 by, Oct 4 2012

We are seeing this problem with chrome frame as well. Most of our networked workstations use XP. We initially thought chrome frame would fix compatabuility issues with IE8 and some of the websites we use as part of our business. unfortunately we are increasingly having to force more and more sites out of the IE interface. We have about 500 workstations and all suffer from the same pepper flash issue - this is very frustrating, is anyone working on this?

You NEED to allow users to permanently disable pepperflash.  It's re-enabled itself every day for the past 3 since I determined it was the cause of my issues.

Comment 57 by, Oct 11 2012

Does anyone know how to disable pepperflash or adobe flash via group policy? I can whitelist/blacklist plugins (i.e. Flash) but I can't find a way to isolate a version of a plugin. If I blacklist flash it removes both pepperflash and adobe flash. If I whitelist it, it enables both. I'd like to try to specify pepperflash via GPO and see if that will permanently disable it.

Comment 58 by, Oct 11 2012

rpetro224, I'd recommend trying to update your graphics driver, if that's possible. I suspect we may have to blacklist that driver version, if it's crashing all the time. You could also try launching chrome with the --disable-accelerated-compositing command-line flag. Could you paste the contents of about:gpu here?

Totally correct. Pepper flash may be safe, but it is slow as hell. It causes my poor pentium 4 heat up so much that i can light my cigarette on it!

3 months, yes 3 months I've now put up with this crap! The disable pepperflash fix works until the next chrome update. It's on my elderly dad's laptop and it means he can't watch online videos. The amount of complaints about this online are legion. What the fuck are you playing at GOOGLE??? 3 months and you haven't fixed this very simple thing. In fact with your latest "update" it's got worse! Now not only won't flash videos play properly but the graphic driver crashes and the machine locks up for ages. You have rendered one of your main products unusable, wasted countless hours of millions of people's time and you are a fucking disgrace!

Comment 63 by, Oct 14 2012

Comment 65 by, Oct 14 2012

I find the latest posts very inappropriate at best. Currently, there is a very easy fix to the issue of viewing online videos by disabling pepperflash.  Since disabling pepperflash, I haven't had any problems watching online videos.  I'm sure that in due time, this issue will be permanently fixed.  In the meantime, let us not forget all of the free tools Google offers, ie. reader, docs, forms, etc.  I just hope they will continue to offer these tools free of charge.  I find Chrome to be the best and fastest browsers to date.

Comment 66 by, Oct 17 2012

Finally saw a difference on Win7 for myself with the Presidential debate livestream; Pepper Flash maxed out a thread with 25% CPU, leading to slight jerkiness.  Switching to NPAPI Flash brought CPU down to 10%.  Interestingly, the CPU usage shows up in the tab process, not the Flash plugin process.

Comment 67 by, Oct 25 2012

I recently switched from Safari to Chrome for various reasons. Some things work better on Chrome. However, almost immediately I noticed that all videos played choppy in Chrome while the same videos played smoothly in Safari. So right now I continue to use Safari for video playback. I wanted to try the pepperflash solution mentioned by some, but it does not appear in in my about:chrome details.

I have users in Brazil claiming the same problem on Windows XP Pro SP3 with Chrome 22.0.1229.94

The problem persists after trying all these steps:
1) Update npswf32.dll on
2) Update Video Card drivers
3) Disabling pepflashplayer.dll at chrome://plugins
4) Adding to the shortcut: --disable-accelerated-compositing

The problem only occurs in full screen (after this changes). Before it was both on normal and full. Chrome:plugins, Chrome:version and Chrome:gpu are on the file attached.

Have you tried the --disable-bundled-ppapi-flash parameter?

Comment 71 by Deleted ...@, Nov 8 2012

In the latest version of Chrome, 23.0.1271.64 m, they removed the NPAPI plug-in and left only the PPAPI one. Now there's nothing to disable and all the videos on YouTube are slow again. Is there any way to reinstall the NPAPI plug-in?

Comment 72 by, Nov 8 2012

Try Adobe's offline Flash installers:

On my end, Chrome updates haven't removed the NPAPI plugin.  (I'm on Chrome 24.0.1312.5 (Official Build 166104) beta-m, on Windows 7 64-bit.)  Maybe it works differently on WinXP or Stable channel...

Comment 73 by, Nov 27 2012

If your audio and video are still choppy in Chrome 23 or higher, please post this complaint at Chrome  Issue 161307  .

In addition to the debugging information that they request at the top of the page, I would suggest posting the results of the following test:

Go to chrome://plugins/
Disable the PPAPI Flash
Make sure NPAPI Flash is enabled. If you don't see NPAPI Flash, download it from
Completely shut down Chrome and restart it.
Watch a video on Hulu.

Then return to the plugins.
Disable NPAPI and enable PPAPI.
Completely shut down Chrome and restart it.
Watch the same video on Hulu.

If you're feeling particularly helpful, download Chrome Canary and try some different buffer settings (powers of two, please) like so:
"C:\Documents and Settings\YourUsernameHere\Local Settings\Application Data\Google\Chrome SxS\Application\chrome.exe" --audio-buffer-size=8192

Comment 74 by Deleted ...@, Dec 2 2012

Same issue with chrome 23.0.1271.95 m version. Its from last couple of months....let me know when it resolved.

Comment 75 by, Dec 4 2012

Initially I was excited when I learned that Chrome would be maintaining a "better" version of Flash Player via the Pepper product/feature.  Unfortunately, on my ION-based nettop, I really do need video decode acceleration, since my two Atom cores don't do a very good job with H.264.  Can someone please fix this?  Otherwise I may be forced to upgrade to a MUCH more power-hungry machine to run full-time.  I will certainly be paying the price on my electric bill each month.

Who would have thought, a poorly-performing flash plug-in could actually cost me additional money every month? ;-)

Comment 76 by, Dec 4 2012

We are currently ramping up Flash Stage3D support for WinXP users on M23 Stable, which should hopefully help for many folks on older hardware. The ramp-up should finish over the next few days.

Comment 77 by, Dec 5 2012

Also an issue on Windows 7-64.  I'm not sure what Stage3D has to do with
it...this feature doesn't relate to the 3D GPU pipeline, but Flash/Pepper
and the video decoding pipeline.  (Not the rendering pipeline; that is
still intact.)

Comment 78 by, Dec 19 2012

I already posted similar results over at  Issue 161307 , but this issue seems to be the same problem with PepperFlash causing high CPU consumption, choppy audio (and in extreme cases "Shockwave not responding" errors) on low-powered machines running any operating system.

When I use Chrome Canary 25.0.1364.0 with PepperFlash enabled, if I attempt to play a video and then load Google News another tab, the audio suffers glitches. If I try to play the video while loading another program, the sound becomes choppy.

When NPAPI Flash downloaded from Adobe is the only enabled version, everything works fine. The problem with PPAPI Flash isn't as horrendous as when it was first included with Chrome updates, but I would have stopped using the Chrome browser long since if it weren't possible to disable PPAPI updates permanently.

Comment 80 by Deleted ...@, Dec 29 2012

I posted this on a different related support thread but I'm going to post it here too in case it helps:

I've been having to disable pepperflash for months as well to watch HD youtube videos.  The problem seems to be that pepperflash doesn't use my gpu to hardware accelerate the videos so then the HD videos get very choppy and the sound clicks and pops as well (and cpu usage is maxed out).  

This is easily verified by opening a 720p or 1080p youtube video.  With pepperflash still enabled...when you "right click" on the HD video as it plays and select "show video info", it will show "software video rendering, SOFTWARE video decoding".  But if you disable pepperflash and just use regular flash, that same "show video info" thing will show "software video rendering, HARDWARE video decoding"...and the cpu usage will be much lower and the video and sound will play smooth.  On a side note, if you play the HD video in full screen with regular flash, it actually will show both "HARDWARE video rendering, and HARDWARE video decoding".  Pepperflash will still use SOFTWARE rendering and decoding for both in full screen though and my computer grinds to a hault with the cpu maxed out.

Hope this helps.

brettw@: we are still getting reports from Chrome 24 users. is there any update? 
Do you need any data to make progress (e.g. about:gpu dumps)? Thanks.

Comment 82 by, Jan 22 2013

26.0.1389.0 canary

I was just checking in to see if this had been fixed. Apparently not. But here is another site to compare PepperFlash with the more functional Adobe plugin.

Using PepperFlash, this 3D model demonstration leaves the processor pegged at 100% and remains stuck on a heavily aliased low-quality version regardless of the quality setting at the top. Rotating the model is jerky. And of course the audio is still terribly choppy.

I need Flash to use hardware rendering in order to get adequate performance. Maybe the systems used by the PepperFlash developers can handle pure software rendering, but /my/ CPU just won't cut it.

Comment 83 by, Jan 26 2013

FYI, report of choppy playback on the following spec.
Is it reasonable to expect no performance regression on this kind of spec?

Windows XP Home Edition	
Intel Celeron M 360 1.4GHz	
Memory 512MB	
Intel Mobile Intel(R) 915GM/GMS,910GML Express Chipset Family
  - Driver 6.14.0010.4764 

I will try to find out if updating the graphics driver improves the situation for that particular user.

Comment 84 by, Jan 27 2013

People who are seeing issues should probably attach a copy of their about:gpu page here, and try to grab a trace (follow the instructions at ) while viewing some Flash that has problems and attach that here as well.

Comment 85 by, Jan 27 2013

Yes, finally some official data collection! I was feeling like a hypochondriac trying to prove a self-diagnosis of flesh-eating fungus by bringing toenail clippings to the doctor.

I have to note that the GPU appears to be fully functional, despite my old hardware, when I run the browser with the flag
I've been using Chrome for a long time now, but I'm going to find myself a less-sophisticated but fully functional browser if the option to disable PPAPI Flash is ever removed before this problem is resolved.

The Hulu tab crashed a number of times while I was attempting to use the tracing function and the tracing tab itself pegged the processor and temporarily hung while processing the data. The warning about keeping logs small was certainly justified.

For each recording, I started the video, started trace, waited, switched to the video tab, waited, experimented, switched to trace tab, and stopped trace. (Or at least that's what I intended to do.)

* Just Hulu
* Loading and unloading a program (Yes, it really took that long. Remember the processor is at 100%)
* Scrolling a window with Google News (with a few accidental hovers)
* Hovering over links on Hulu and then on Google news

GPU pages:
* Chrome 26.0.1395.1 canary
* Chrome 24.0.1312.56 main, with PPAPI disabled

Easy steps to reproduce sound chopiness issue :
* Listen to music on using pepflashplayer plugin
* After a few minutes the sounds becomes all choppy and stays that way
* Restart Chrome and disable pepflashplayer plugin (leaving adobe's enabled)
* Listen to music on
* Everything works fine

I think most of the problems are with the new Pepperflash player mac/windows, not Chrome, even though Chrome does have some issues. I don't see hardly anything in the Adobe Bugbase about it. I have Bug-3495015 open on this now.
Please add comments if you have flash problems & the most important thing is to add your own bug with Adobe. I believe this will speed up the fixes in Pepperflashplayer.

Here is the solution for Linux Chrome, maybe it works also on MS Windows: .
In about:flags you need to enable several items so fullscreen HD youtube flash video can be played by pepperflash with hardware accelerated rendering.
It works for my lubuntu 13.04 and google-chrome-beta and nvidia video card: no more glitches!
I think the reason why hardware acceleration was disabled was because of bad amd/ati video drivers, so it may not work if you have an amd video card. I'm also not sure if I will now not risk other possible problems because of enabling these flags, the nvidia drivers aren't flawless either.

Even i have observed this issue in mac and windows OS.
If PepperFlashPlayer.plugin is disabled and player is loaded in full screen mode , playback works fine with no issues.
But PepperFlashPlayer.plugin is enabled and player is loaded in full screen mode,  playback not smooth, video freezes all the time, audio and video not in  sync with each other.

[Environment Details]
Mac OS : OS X 10.8.6
Windows OS : Windows XP,7,8
Browser Details : Chrome 29.0.1547.65
Flash Player : 11.8.800.97

Brett's definitely not working on this, so unassigning and CCing other people who might care.

It sounds like it's probably a problem with unsupported video cards, meaning we aren't doing hardware-based video decode. With this bug being for Win XP, I suspect we should set it to "WontFix".

Status: WontFix
I agree. Lets WontFix this for XP. See also  issue 335662  for Windows 7+.

This affects me, Win7 so it is not isolated to XP.

Also "Adblock Plus" does not support the NPAPI ("real Adobe") plugin so I have a choice between good performance that wastes my time advertising things I'm never going to even slightly buy, or choppy 10-12fps slideshows in PPAPI with no ads, OR I guess almost-fullscreen as if I CTRL+roll to zoom in it doesn't get much choppier even though it's 90% the same as full-screen size.

I am mostly trying to watch things on Comedy Central sites.  But it does it basically anywhere.  The hardware accel option in the Settings... menu does not appear to have any effects at all on my system.

Choppy video in chrome both regular and full screen.  I disabled pepper flash as recommended by some but no use.  I really like chrome but as of now I am switching back to explorer until Google fixes this problem.  This problem is evident with H.264 video that have motion such as pans and tilts.

Chrome Version-34.0.1847.116
Operating System- Windows 7 Premium
Type of video card-NVidia GeForce GTX 780 Ti
Video card driver and version-
Examples of exact URLs where this happens-Any video anywhere on Google Chrome

This doesn't happen with any other browser.  Just Google Chrome.  Plus I know it is not my graphics card because it is one of the worlds fastest graphics cards.  Its just for Google Chrome.

I'm going to turn off comments here. If you see issues on other OSes, please file a new bug; this one is specific to XP.

@Comment 103, since you're on Windows 7, that's a different issue. You might want to file a new bug and append what you see if you navigate to "about:gpu".
