Issue 876523: Blackrectangles flickering, huge memory and cpu allocation during being inactive, security

Reported by oom...@gmail.com, Aug 21

Issue description

UserAgent: Mozilla/5.0 (X11; Linux i686) AppleWebKit/537.36 (KHTML, like Gecko) Ubuntu Chromium/68.0.3440.106 Chrome/68.0.3440.106 Safari/537.36

Steps to reproduce the problem:
1. Browse on websites
2. Happens quasy randomly
3. General experience when shifting to a specific new site

What is the expected behavior?

What went wrong?
Black flickering rectangles appear.
The tabs and addressbar gets partially or totally covered by this/multiple black rectangle, clicking over the area remains possible. Sometimes this black/other color flickering also appears over other areas of browser.
Sometimes I hear the cpu vent rpm going up and cpu getting hot, the comp slowing down. Checking 
$top
on bash tells me that chrome is eating all the memory and cpu, when I start monitoring sometimes the unusual behavior drops.
Sometimes chrome freezes out my whole computer.

Also it seems I cannot get clamav working, even tried tips from stackexchange to get the workaround done

Did this work before? N/A 

Chrome version: 68.0.3440.106  Channel: n/a
OS Version: Linux Alice 4.15.0-32-generic #35-Ubuntu SMP Fri Aug 10 17:55:48 UTC 2018 i686 i686 i686 GNU/Linux
Flash Version: not sure

I have a suspicion of having a RAT or other malicious software, and chrome and javascript running in chrome might be also a tool in that.
Reasons for suspicion: the anomalous activity seems to arise if I visit specific websites, more related to politics.
I also experience anomalies in skype(using browser version) on certain keywords like signal/communication failing for a few seconds.
I had an experience that my screen went crazy not much longer after I wrote a public comment(I don`t write personal comments generally), and lines of colorful(colors of noise) pixels quickly flickered starting from the position of my cursor and going downwards and rightward.
I think I browse quite safely, use adblock, don`t download all kind of stuff.
Sorry, maybe not all this is your responsibility, just feeling a bit lost.

Tried to test this issue on reported chrome 68.0.3440.106 using Ubuntu 17.10 and 14.04.
Steps:
-----
1. Launched reported chrome
2. Navigated to some popular sites like " https://www.wikipedia.org/ ", " https://edition.cnn.com/ " and " https://www.firstpost.com/category/politics ".
As we are not seen any Black rectangles flickering 

@Reporter: It would be really helpful if a sample URL is provided, so that we can investigate the issue further. Can you verify this issue with fresh profile that is not having any extensions and apps or reset all the flags. Let us know whether issue still persists.

Thanks...!

Comment 3 by oom...@gmail.com, Sep 2

Thank you for considering my bug report.

Website URL examples: index.hu hvg.hu origo.hu youtube.com web.skype.com . 
Since this report, I have not experienced the black rectangles issues.
Memory and cpu leak issue is still experienced (notice: I usually have 10+ tabs open). Freeze still happened. The anomalous experience is more related to content/activity than url. Also the anomalous experience is not a 1-1 correlation, only >0 correlation.
Switched to firefox and using track/cookie/ad blockers. 
Firefox seems more stable( youtube is slower there )

I will update here, when I have tried with a fresh chromium without extensions.

Thanks.

This sounds like an issue that I've been experiencing. Please see this. https://productforums.google.com/forum/#!topic/chrome/nlHrXqvFomY

Comment 6 by matthewj...@gmail.com, Sep 3

In any case, this issue with the black rectangles, flickering and other anomalous behaviors is being reported by multiple people on the product forums, I will try directing people to leave their comments on this issue on this page instead of the product forums.

Comment 8 by jalov...@gmail.com, Sep 3

I can confirm the display issues here.

Chrome v68.0.3440.106 (Official Build) (64-bit)
Ubuntu 18.04.1 LTS

As the OP said, it seems to be a "lots of tabs open for a while" issue rather than specific to any sites. I'll be browsing normally, move the mouse, and suddenly the window elements (i.e. tab bar, bookmark bar, toolbars, etc) start glitching. It's static until the mouse is moved, and then it looks like it's having trouble deciding which parts of the window to draw where.

The window still behaves as if everything is where it is normally, thank god.

Comment 9 by matthewj...@gmail.com, Sep 4

I just had this issue happen again. See attached screenshot. 

Google Chrome Version 68.0.3440.106 (Official Build) (64-bit)
Ubuntu 18.04.1 LTS

Moving the mouse over the affected areas makes the corruption of the UI more pronounced.

This issue also affects 
Google Chrome Version 69.0.3497.81 (Official Build) (64-bit)
Ubuntu 18.04.1 LTS

I noticed that this issue has been classified as GPU related. In that case I'll also provide my system information.

Via lshw, here's my GPU info.

It's important to note that people rocking a GTX 1080 have also reported this issue.

Copying and updating my response in the google forum thread https://productforums.google.com/forum/?utm_medium=email&utm_source=footer#!msg/chrome/nlHrXqvFomY/ETRPPvUbBQAJ

Got exactly the same issue. Occurs (I thought) randomly, but people are mentioning it's roughly time based and I can see that is likely true for me too. Unless it's just because running it longer = more chance of seeing it. Only solution was to close Chrome entirely and reopen. Happens when using a theme that is not default (I tested a lot of only dark type themes). Started about 2 weeks ago after being perfect forever. 
Chrome Version 68.0.3440.106 (Official Build) (64-bit); GTX 1080; Ubuntu 16.04.5;

From these replies, I saw in Software & Updates > Additional Drivers, that I have been using xserver-xorg-video-nouveau drivers; I don't recall specifying but thought I had originally setup using the NVidia drivers, so perhaps this setting was changed and initiated it all.

Have changed to NVidia driver (04/09/18) and not seen issue yet (06/09/18), same usage / behaviour eg operating 12hrs / day with many tabs, console open, developing a site playing ~ 42 videos at once with heavy js and css effects, crashed a tab several times, using "Material Dark" theme (touch wood).

Comment 14 by lukealle...@gmail.com, Sep 13

I've been seeing the same issue for a month or so with Ubuntu 18.04, Nvidia GeForce GTX 980, Chrome Version 68.0.3440.106 (Official Build) (64-bit)

Reinstalling Chrome didn't fix it. The issue doesn't occur on my Ubuntu 16.04 laptop.

One thing I've noticed that might be helpful: if I drag a tab out of the corrupted black area, so that Chrome makes a new window containing that tab, the new window is not corrupted. I can drag all the tabs out, one by one, into the uncorrupted window. So the corruption is a property of the window, not the tab.

I've only seen this problem in Chrome, no other programs. (Though I don't have any other programs that draw tabs on the application's top bar like Chrome does.) I'm switching to the proprietary Nvidia driver to see if that fixes it.

Comment 15 by arvoe...@gmail.com, Sep 13

I'm seeing this issue too on a brand new Ubuntu 18.04 installation with Chrome Version 69.0.3497.92 (Official Build) (64-bit). I have not done anything to my computer other than install chrome and open it. Problem typically appears after opening up 15 tabs and browsing for a couple hours. If there are multiple windows (not tabs) open, the problem can occur in one window but not the other. Dragging it around the screen or resizing the screen (since the buttons are still clickable) does not change which parts are being masked by black rectangles. I have tried `sudo apt-get install nvidia-340 nvidia-settings` and will see if that fixes the problem.

Comment 16 by arvoe...@gmail.com, Sep 14

Update: `sudo apt-get install nvidia-340 nvidia-settings` did not fix the issue for me. It happened again right after I opened up 5 GitHub tabs in quick succession.

Hi guys, I'm on vmware Workstation player with an ubuntu 18.04 downloaded from osboxes. I usually experience this after a couple hours working with several tabs open. Just letting you know so you can easily replicate it.

Comment 22 by zmo@chromium.org, Sep 17

Sorry, but if you are using nouveau driver, we won't provide support because that driver is unstable.

Anyone else experiences this and uses proprietary NVidia driver?

Comment 23 by matthewj...@gmail.com, Sep 17

zmo@chromium.org

The nouveau driver comes with Ubuntu out of the box, in the LTS version. It's my understanding that the software that comes with LTS is "Mature", so why does Google consider nouveau to be unstable? Below is my GPU information.

Comment 24 by sdj...@gmail.com, Sep 17

Matthew,

I understand the chromium project's position on this. The issue is really with Nvidia. Unlike Intel or AMD, Nvidia does not provide open source drivers to the kernel so the community developed nouveau drivers do not have the support of the proprietary driver and therefore do not have the same degree of stability or performance. I thought I was running the proprietary driver until it was pointed out to me because I had activated it in the update ppa settings. I discovered that I had to disable secure boot in my bios and disable the Wayland login screen to get the proprietary drivers working (https://askubuntu.com/questions/1031511/cant-disable-nouveau-drivers-in-ubuntu-18-04). Hopefully that will address the issue that I have with Chrome. Thank you for the assistance on this matter.

Comment 25 by arvoe...@gmail.com, Sep 18

I am also using the nouveau driver. See the attached file (it was too long due to error messages).

If Chrome's official stance is to not support this driver, then, since it is already able to detect its use under `about:gpu`, could it at least provide some kind of warning message together with a recommendation about how to update/remove the driver to one that is supported? IMO, it's not the best user-experience to leave us uniformed and on our own with an out-of-the-box Ubuntu installation. Thanks!

Comment 26 by zmo@chromium.org, Sep 18

We thought about blacklisting nouveau driver long time ago, and decided to let more adventurous users to play around. Now that Ubuntu ships with nouveau on default, maybe it's time to blacklist it in Chrome.

piman@, kbr@, vmiura@, let me know if you have objections. Otherwise I'll land a CL to blacklist GPU acceleration on Linux with nouveau drivers.

Comment 27 by matthewj...@gmail.com, Sep 18

As a question. Is Chrome's UI GPU Accelerated? With the Nouveau driver, there aren't any problems so far with it rendering web pages. The corruption or black box effect only occurs on the Browser UI. So if there is a way to disable GPU acceleration for the UI itself and not in the web page rendering viewport, than that might be an effective solution.

Comment 28 by zmo@chromium.org, Sep 18

We received quite some bug reports on other rendering issues with Nouveau, and this bug is just one of them. So we will disable all GPU acceleration by default. If someone wants to bypass that, there are two options:

1) install proprietary NVidia drivers (see #24)
2) run Chrome with --ignore-gpu-blacklist, but be aware you are taking a risk here

Comment 29 by piman@chromium.org, Sep 18

Components: -Internals>GPU Internals>GPU>VendorSpecific
@#27: on linux the UI (currently) uses the same acceleration modes as pages (i.e. GPU-composited, but software-rasterized + uploads to GPU).

Comment 34 by pendingc...@gmail.com, Sep 23

nouveau got a fix (or workaround) for similar issues with many applications in Mesa 18.2.0: https://gitlab.freedesktop.org/mesa/mesa/commit/f310e86a420.patch
This issue seems to happen exclusively on Maxwell and Pascal cards on pre 18.2 Mesa, so perhaps using Mesa 18.2 or 18.3-dev or applying the patch on older versions might fix the artifacts.

Comment 35 by ibmir...@gmail.com, Sep 26

Does this change only affect regular web page rendering, or does it also disable WebGL? Hopefully the latter is still available.

It's unfortunate that you'd make this sort of change unilaterally, without any sort of project involvement or feedback. This can lead to escalations like "make nouveau appear to match a different driver when running chromium". It's important to work together, not against each other.

FWIW, I've been using chromium on nouveau for about 5 years on a wide variety of NVIDIA hardware (from G96 through GP108), with almost no issues.

Comment 36 by zmo@chromium.org, Sep 26

This puts Chrome on Linux with Nouveau onto SwiftShader when rendering WebGL contents.

Comment 37 by piman@chromium.org, Sep 26

WebGL would be available via SwiftShader (in software).

Unfortunately we don't have the resources to test every variation of every GPU/driver combination on linux, let alone investigate & fix bugs in drivers.
We want a stable & secure browser first, a GPU-accelerated one second, only if possible.

The default driver on Ubuntu LTS has severe issues, asking non-technical users to update their driver is just not acceptable as a prerequisite to use Chrome.


If someone is interested in well-scoping the brokenness (version range and/or devices affected), we're happy to take a patch to the blacklist.

Comment 38 by ibmir...@gmail.com, Sep 27

So basically you're blacklisting accel for all nouveau users on all GPUs because some GPUs don't work with some old version distributed with some distribution.

I'm sure that's exactly what you'd do if someone came in with issues with the NVIDIA or Intel or AMD drivers crashing or misrendering with the default version shipped in Ubuntu LTS.

Sigh...

Alright. I'll have to figure out how to properly respond to this. Since you explicitly don't want to support nouveau (comment #22), I guess the proper solution is to make nouveau report "NVIDIA" for the vendor when running under chrome/chromium. Otherwise I'm just playing whack-a-mole trying to undo these blacklists.

Let me know if you think my analysis of the situation is off here.

[Here's what I'm trying to avoid: all the support issues that arise because someone goes to some WebGL page in Chrome and it's slow/not-working because of the blacklist.]

Comment 39 by zmo@chromium.org, Sep 27

Over the years we receive many bug reports related to nouveau driver statibility, so we draw the conclusion nouveau is unstable not just from this bug report, but from a aggregation of many.

As mentioned in #37, we don't have the resources in house to test and debug nouveau related issues. If community can narrow down a finer scope, we'll reconsider.

I wouldn't recommend faking driver vendor. First, NVIDIA is a brand and I am sure there are legal issues. Second, once trust is lost, it's hard to regain it.

Comment 40 by ibmir...@gmail.com, Sep 27

Yeah, the trust bit goes both ways, of course.

And much as you don't have resources, the nouveau project is also not exactly flush with people desperate for things to do like figuring out how to improve shotgun-blacklists in various software, esp software whose authors appear hostile to the project. One tends to rely on distributions to do the software integration -- if the distribution feels like nouveau is good for its users, you should respect that. If individual pieces of software hack around that, the whole system breaks down.

It's an unfortunate situation all around. I'm sure we're all trying to achieve the best outcome possible with the resources available, based on our perceptions of what is best. You appear to have dropped the bomb on nouveau, from where I'm standing. I'm wondering if I have anything other than the nuclear option left. I guess we can also just keep this as a "known issue" and tell people to use a non-chromium-based browser. Not ideal either, esp as it's still my preferred browser.

You probably won't accept patches to the blacklist as-is, you'll want some kind of proof, guarantee, whatever... I don't have time for all that. There's no governance around the blacklist, so it's just a black hole. Sigh...

But let's try it, perhaps it's not as hard as I'm perceiving it to be. As mentioned in comment #34, the misrendering issue most likely affects just GMxxx and GP1xx GPUs with mesa prior to 18.2. You can figure out which GPU it is by matching the GL_RENDERER for "NV1[123][0-9]" (NV117 = GM107, NV138 = GP108 for example). Happy to review a patch.

Alternatively would you consider reverting the blacklist patch, and auto-closing all issues that mention nouveau with a redirect to nouveau@lists.freedesktop.org?

Comment 41 by zmo@google.com, Sep 27

Before taking any further actions on our side, we'd like to verify the quality of nouveau a bit.

Can you run WebGL 2 conformance tests on a GPU / driver you think is good, and send back the results?

https://www.khronos.org/registry/webgl/sdk/tests/webgl-conformance-tests.html?version=2.0.1

You can uncheck the all/deqp/functional/gles3/builtinprecision section because that part of tests are potentially buggy.

If a test triggers a crash, you have to uncheck it, and restart the run from the beginning.

This should give us a good sense how stable and conformant the nouveau driver is.

Comment 42 by piman@chromium.org, Sep 27

@#40 we could go in detail about what we'd like from the nouveau project to make it a first class citizen, but I don't think this bug is the right avenue. If you're interested please feel free to contact us on graphics-dev@chromium.org, or privately, or open a separate bug.


But let me reiterate what I said in #37: we want a stable and secure browser first, and a GPU-accelerated one second.

The default driver on the distribution we support is broken. This is out of our control, and out of our end users' control. We still want to provide them with a stable and secure browser, and if we can't do that with GPU acceleration, then we do that without. That's what the blacklist is for.

Users that run alternative distributions and/or are willing to modify their system to install a patched driver are free to do so, and will be savvy enough to run chrome with the extra --ignore-gpu-blacklist flag. We just don't provide support for that configuration.

Having the nouveau project fake the GL_RENDERER in drivers it releases sounds like it would be a disservice to users and break more than it fixes.


Again, if someone wants to spend the time to test thoroughly to narrow down the blacklist, we will accept patches. This is just not work that we're going to do ourselves.


This bug is marked fixed, I would like to keep the bug open to comments so that users can comment on whether or not the bug is fixed for them, please refrain from commenting about the blacklist decisions here (see above for other avenues) so that we don't have to lock this.

Comment 43 by kyle.l...@gmail.com, Jan 5

This issue has nothing to do with chromium as it happens all the time with any 3D gfx in a DE. This is not a new Nouveau issue and has been plaguing the OSS driver for many many many many years. Completely reproducible on a GTX460 and a GTX 750 Ti.

Please remove the blacklist as all Nouveau users expect this corrupted behaviour. If at all possible it may be worthwhile to let users know it doesn’t have to be this bad if they flip to the binary driver. Perhaps a pop up letting them know?
