Chrome causing weird flickering since upgrade to 85.0.4183.83

In my case, I go to chrome://flags/

Then enable:

#ignore-gpu-blacklist
#enable-vulkan

I don't know if there will be any problems later, but it works for me now.


I raised a bug ticket for this:

https://bugs.chromium.org/p/chromium/issues/detail?id=1122224#c14

There is already a workaround:

Run with --use-gl=desktop or --use-cmd-decoder=validating

Btw unrelated to this problem, I see your system is using 'ati,fbdev' drivers and DRM 2.45

AFAIK your card should be using either amdgpu (note: the open source driver is called amdgpu, the closed source driver is called amdgpu-pro) or radeonsi, thus enabling DRM 3.x and you should see improved overall graphics performance. The ati driver is a really, really old one.


This issue is fixed in Chrome 86. Please remove workarounds suggested in the other answers especially --use-gl=desktop and --use-cmd-decoder=validating. What those workarounds do is revert to a deprecated renderer. Continued use of that renderer would reduce testing we get from the new more versatile renderer.

Since enabling Vulkan was also suggested as a workaround, I'm personally glad you are trying it out, but beware that the Vulkan implementation is not yet widely tested and isn't considered ready for users. If you do continue using Vulkan, please file bugs under https://crbug.com/new.

Also, to prevent such issues in the future, please consider using (or occasionally trying out) Chrome Beta. The issues there can be fixed in the same version and before reaching the wider audience. To install Chrome Beta: sudo apt install google-chrome-beta.

Cheers!
