I have done additional tests:
1. The computer does not hang with 6900XT instead the screen flickers
when moving the cursor.
2. The computer does not hang with 7900XTX if I turn off VRR. But the
screen flickers when moving the cursor, as on 6900XT.
To enable VRR, please set 'variable-refresh-rate' in
experimental-features, and in the Display setting, enable Variable
Refresh Rate.
$ gsettings set org.gnome.mutter experimental-features
"['variable-refresh-rate', 'scale-monitor-framebuffer']"

3. The chances of the problem reoccurring are much higher when running
the game "Play Innocence Or Money Season 1 - Episodes 1 to 3". There
is a free demo version.

Yes. This didn't help.

This patch also didn't help.

Maybe try to compile a kernel with the same config as mine and enable
VRR to repeat the problem?
I attached my build config to this message.
