1743505 - Completely hangs the system when watching videos on linux

Status: UNCONFIRMED

(Core :: Graphics: WebRender, defect)

Attachment: about:support

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:91.0) Gecko/20100101 Firefox/91.0

Steps to reproduce:

After 20-30 minutes everything hangs, the sound stutters, the system does not react to the keyboard, mouse.

If you set layers.acceleration.disabled = true in about:config then the hangs are very rare, only after 5 hours of watching video.

Now I have installed "gfx.webrender.force-disabled = true" for two days without any hangs.

I concur, sounds related to bug 1735905 based on the symptoms of the duplicates.

Please re-test with 91.4.0 ESR

The problem is still there. The only difference is when "layers.acceleration.disabled = true" the whole system hangs except for the mouse.

The problem was solved by replacing the VGA cable, now my resolution is 1280x1024.
