Video artifacts and no video output after starting a game

Hi everyone. I’ve just installed cachy on my pc (Ryzen 5 3600, AMD Radeon 6600 XT). I followed the gaming instruction but, when I launch a game, I have weird artifacts and from time to time no video at all (like I’ve removed my hdmi). I tried searching online for that issue but I’ve not found anything. When I was on mint I didn’t have that kind of problem. Do somebody know to fix this issue?

I tried also to download xonotic to have something outside of steam and I have the same kind of problem.

Kernel: Linux 6.13.6-2-cachyos
Display (C24F390): 1920x1080 @ 60 Hz in 2]
DE: KDE Plasma 6.3.3
WM: KWin (Wayland)

Fixed on discord: it was kwin wayland problem. Tomorrow we’ll do a bug report.

With X11 works fine.
