As Bug 1372850 Comment 2 said, we should also follow Bug 1372850 Comment 3 on Linux platform.

Those harmless gpu process crashes went away by setting layers.acceleration.force-enabled back to false (default), I think.

(In reply to Darkspirit from comment #2) > Those harmless gpu process crashes went away by setting layers.acceleration.force-enabled back to false (default), I think. No crashes because of that for 1 day now. For the record: Disabling the gpu-process on my Debian Testing x64 (Radeon RX480) with Webrender + Webrendest enabled is not an option: Normally I get some tab crashes or "permanent graphical random inside the window" with background crashes like bug 1352092 I could normally fix by pressing Ctrl+W. I made a small test and disabled the gpu-process: My whole browser crashed on every webrender/webrendest bug. Resetting layers.acceleration.force-enabled yesterday was a fine solution, I only had webrender tab crashes so far.

Reproduced STR of bug 1352092 comment 11. layers.gpu-process.force-enabled;false layers.gpu-process.enabled;false

I haven't seen this for a long time.
