(Wanted to assign this to component:Internals>Plugins>PDF but seemingly I was never given the option to select it)

Tested the issue on Mac 10.10.5, Windows 7, Ubuntu 14.04 using 49.0.2623.75 with below steps:

Same here:

OSX 10.9.5
version 49.0.2623.75 (64-bit)

Using all those pdf files
http://www.tcpdf.org/examples.php

We are seeing this issue in our organization as well. It appears to have started last week. I've just seen it live today.

I simply used the US governments 1040EZ tax form.

https://www.irs.gov/pub/irs-pdf/i1040ez.pdf

I have attached a video of the issue as it is occurring. I was also made aware earlier this morning that a print preview of a pdf appeared "completely blank" for one user and a screenshot of that is also attached.

I also disabled several of the user's extensions (including evernote) that I thought may be confusing the issue.

Could someone put the word "gray" into the title of this issue and remove Needs-Feedback?

This issue isn't present on another OS X 10.9.5 machine with Chrome 48.0.2564.116 (Official Build) (64-bit).

Various reports of this in the Chrome help forum: https://productforums.google.com/forum/?utm_medium=email&utm_source=footer#!msg/chrome/UyfmhFzQj4c/CfeqfZfaCgAJ

It does appear to have started with Version 49.0.2623.75 (64-bit) on MAC for several folks.

Thank you for providing more feedback. Assigning to requester "ssamanoori@chromium.org" for another review.

Adding that this issue still occurs on 10.9.5 / 13F1603 with Chrome 49.0.2623.87.

Have not verified with other versions of OS X yet.

In the link provided by etcohen there is a common theme of users seeing the problem being on OS X 10.9.5 coupled with Chrome 49. In that link one user also says upgrading to OS X 10.11 resolved the problem.

We are seeing the same problem.  OS X 10.9.5 with Chrome 49

Various folks in the productforums thread (link above), starting with user12347, are reporting success with a work-around:
    I have this issue as well (mac os 10.9.5, chrome  49.0.2623.87 (64-bit))

    Unchecking Preferences > System > "use hardware acceleration when available" seems to have fixed it, so hopefully hardware acceleration is generally not available on my system :-)

I can confirm that the unchecking of "use hardware acceleration when available" fixes the issue (on two macs ... we have another 3-5 users with this issue).

+current / next mac bug triager

Unable to reproduce on MacBook Pro with Chrome 49.0.2623.87, with hardware acceleration option checked. Does the issue occur in the latest Canary?

Yes, this issue still exists in the latest dev and Canary.
(with hardware acceleration checked)
Tried both
51.0.2679.0 dev
51.0.2685.0 Canary

OS X 10.9.5

 Issue 595963  has reported the same problem(merge suggestion)



ps: I thought an issue I reported recently  Issue 596010  is related but it turned it was not quite since with hardware acceleration unchecked, it was still there.

I'm able to reproduce the issue on a MacBook Air (13", mid 2012) running OSX 10.9.5 with the latest Canary (51.0.2685.0 canary, 64-bit).

 Issue 595963  has been merged into this issue.

Could someone who is seeing this go to chrome://gpu, and attach what you see there?

I wasn't able to reproduce on 10.9.5 (13F1134), with
 - https://www.irs.gov/pub/irs-pdf/i1040ez.pdf
 - MacPro5,1 (Radeon HD 5770), non-retina screen
 - scrolling with each of: {bluetooth trackpad, mouse wheel, scroll thumb drag}

Tested:
 - 48.0.2564.116 [before regression]
 - 49.0.2623.87
 - 51.0.2685.0

There's probably something here - maybe something similar to  Issue 543324 . Not sure why this would be specific to PDF though. Also seems to be specific to 10.9 (so if it's an option - taking the free upgrade from Apple to 10.11 would give you the best fix).

ccameron@ probably knows what to do (maybe we need something like r358579?

I'm affected and here ist my chrome://gpu output.

Definitely  issue 594343 .

Here is another gpu output. Disabling hardware-acceleration has been our workaround for 10.9.5 clients for now.

Another Mac Book Air gpu output file. I am using Kami extension PDF viewer as a workaround.

I re-enabled hardware acceleration and it is still present.  
Version 49.0.2623.87 (64-bit)
Things I have noticed.
Machines with heavy processing power are not as deeply affected by this. I have encountered about 10 users including myself that had this happen. ON my machine, I was still able to print and kind of view the files if I scrolled.  a user with half the ram of my machine can not do anything. I also see that this is not an immediate issue. As in something triggers this to happen, then it is there until acceleration is disabled.
thanks for the workaround for now though it is much appreciated

version 49.0.2623.108 (64-bit) the issue is not present

Version 49.0.2623.110 (64-bit)
Mac OS X Version 10.9.5

Still an issue; turning off hardware acceleration continues to provide a temporary fix.
