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']" https://postimg.cc/PvXYdvGR 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. https://store.steampowered.com/app/1958390/Innocence_Or_Money_Season_1__Episodes_1_to_3/ Demonstration: https://youtu.be/XIe0pQYPVUo > > I have a few suggestions: > > First, can you also open an issue on the amd gitlab tracker?

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. -- Best Regards, Mike Gavrilov.
