Corrupt graphics in Firefox using AMD embedded graphics

[MAFoElffen]

Please show the results of these, posted within CODE Tags:

sudo lspci -nnnk | grep -A3 -E 'Display|VGA|3D'
grep . /proc/cmdline
lsmod | grep 'amdgpu'
modinfo amdgpu | grep -E '^filename|^description|^firmware|^depends|^parm'

It should have Radeo Vega and be using the amdgpu opensource driver with modules built from from linux-firmware

I think I wore the OP out yesterday.....lol

I was just resting!

Sorry not to have replies to those commands (I'm not near the "problem" computer right now), but earlier I revisited the issue and discovered that it seems to only affect Snap packages... I noticed there is a Chromium (not Google Chrome) package that is also a snap, and that also renders with a corrupt window.

Googling that issue pulled up the following:
https://bugzilla.mozilla.org/show_bug.cgi?id=1847175
https://bugs.launchpad.net/ubuntu/+s...x/+bug/2004532
https://superuser.com/a/1813091

^ the last one provides a way to start Firefox in a non-GPU assisted mode which works around the problem! I'm guessing really I'm waiting for that launchpad.net bug to be fixed... but that might be a long wait.

Until that Bug gets a fix, will this work currently:

firefox --disable-gpu

I know how not fun a problem like this is to a user.
