User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:71.0) Gecko/20100101 Firefox/71.0
Steps to reproduce:
Nothing, Its completely random when it happens and clicking within the glitches area is often enough to fix it, if not minimizing the window and reopening it is.
Actual results:
UI glitches out with random blocks all over the UI and sometimes the page. (in example firefox UI and reddit's header glitch out)
At first I thought this was just an issue with my home PC since I added a new AMD 5700xt and thought it might be a driver issue, but this is my work PC and it has an nvidia GPU in it, so im confident its a firefox issue.
Expected results:
Nothing
Hi
I tried to replicate the issue using windows10 64bit and the latest Firefox release 71, but i donΒ΄t have the problem.
Perhaps one of the addons that you have installed is causing an issue. Do you have a full list of addons installed?
Please share with us the exact link where the issue is happening to you, or it happens on any site?
Also i noticed you are using a dark theme, is that the default dark theme that you set on firefox hamburger menu > Customize?
Please download the latest Firefox Nightly release from here: https://nightly.mozilla.org/ and retest the problem.
If you still have the issue please create a new profile, you have the steps here:https://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles?redirectlocale=en-US&redirectslug=Managing-profiles#w_starting-the-profile-manager
Lastly test if the issue is reproducible in safe mode, here is a link that can help you:

Hi, The list of plugins I have enabled are these: https://i.imgur.com/Nl2qCIV.png
As for testing it, its completely random when it happens. Can take days until it happens, if it helps, I often have my browser open for days at a time.

The priority flag is not set for this bug.
:jimm, could you have a look please?
For more information, please visit auto_nag documentation.
I can confirm this issue, it's completely random.
I'm struggling with it since 71.0 update (currently I'm using 72.0.2).

Can you attach the contents of your about:support as a text file?

Thank you - it looks like this is a WebRender bug, and similar to other reports we have been seeing. Would you be willing to try out Firefox Nightly for a while: https://www.mozilla.org/en-CA/firefox/channel/desktop/ to see if it happens there? If so, I will send you some further instructions that might help us collect more info about this bug.

Awesome, that would be awesome.
After you download Nightly, can you go to about:config (just type it into the address bar). Search for a pref called gfx.webrender.panic-on-gl-error Can you change the setting on that pref so it is enabled, and then restart so it takes effect?
When this flag is set, any time the GPU driver reports a GL error, we will detect this and panic (controlled crash) the entire GPU process. It shouldn't take the entire browser down, just the GPU process (I believe the GPU process is enabled on Windows and Linux, not sure about Mac).
If you see the bug occur while that pref is active, and then restart the browser, the logs from the GL error should be visible in about:support and you can send us the contents of that.
If you see the glitch occur while that option is active, we can infer a few things:
- If there is no GPU process crash / output logs, then no GL error is being reported (likely signals a driver bug).
- If there is a GPU process crash, the logs should give us a clue as to what is occurring (even if nothing is logged, it would still be a clue there is a GL error occurring).
