--- Comment #4 from Hexagon <apricus at posteo.net> ---
I can confirm this problem. My setup:
- Using Arch Linux (Kernel linux 6.1.4.arch1-1)
- Using KDE Plasma (Wayland): plasma-wayland-session 5.26.5-1
- Processor: AMD 5900X, GPU: AMD Radeon 6900XT, MESA drivers

My findings:
- The problem is new. 3 weeks old max I think.
- The problem is hard to reproduce. It randomly occours sometimes every 30
minutes, sometimes 2 hours without a stutter. The stutter is very short (about
800ms). During this stutter the complete desktop hangs including the mouse
cursor, audio (pipewire), playing video or anything else you have open. I have
encountered it dragging Wayland applications like Dolphin over the screen,
playing a fullscreen YouTube video with Firefox (Wayland), playing Minecraft
(Xwayland), playing games through Steam like CS:GO (linux native), playing
games through WINE like The Witcher 3, listening to music with Elisa and more.
It is very annoying and makes consuming multimedia content (especially with
sound) extremely frustrating, wondering when it will hang the next time.

It feels like there is a buffer of some sort running full. (just speculation)

If you need further information, don't hesitate to ask. I hope the problem can
be found soon :)
