1720388 - Firefox not repainting on Linux if I use webrender and some other programs together (KDE/EGL/X11)

Status: RESOLVED DUPLICATE of bug 1712665

(Core :: Widget: Gtk, defect)

Description

[maboroshinokiseki]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:89.0) Gecko/20100101 Firefox/89.0

Steps to reproduce:

Open Firefox with webrender enabled.
Open another program, such as looking-glass-client and The Witcher 2 with proton.
I am on laptop, tried to run them on same GPU and different GPU, all the same.

Actual results:

Firefox stops rendering it's UI and webpage, but everything else is normal, YouTube video is still playing (I can hear the sound, but no graphic), I can open, close tabs, and close Firefox window.

Expected results:

Well, should render graphic properly.

Can you try to disable GL WebRender? With latest nightly, go to about:config, set gfx.webrender.software to true and restart Firefox.
Thanks.

Does Firefox render the page again if you hover it?

Sometimes, I see something similar when playing Minecraft: The YouTube video (VAAPI) is still playing and visible (in my case), but everything around it becomes plain black. I can fix it by hovering the page.

Thanks.

If I set gfx.webrender.software to true, Firefox will repaint correctly after I played some games.
