From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Mostly curious here, can you elaborate on the issues that are fixed with a reboot?
Is it related to poor performance or other aspects of the diaplay like VRR? Can you tell us which games this has happened with?
Sure, I can give some pointers. DE is KDE Wayland and the version is whatever Endeavour gives. AMD 7900 GRE and 5800X, no configuration on drivers/proton. There have been weird "seeing through" application epilepsy things to games runnning extremely poorly until the system is restarted.
There are others like shaders/models glitching out where a restart is also necessary, though I can't confirm if it has been the game or the system itself. Either way, sometimes just restarting the game or changing proton version has fixed them, but they re-appear with different ways to "fix" them in other games. That is, until apt/pacman upgrade which sometimes breaks the fix.
What do you mean by "apt/pacman"? Which one are you using?
That sounds like changing the main config file instead of a conf.d/ sub config file. I have no clue what the correct naming for this is.
If you're running the most recent kernel, I'd recommend moving to linux-lts. I have slightly similar specs, KDE Wayland, 6900 xt and 5800, and I had issues with games straight up crashing out my PC on the latest kernel.
Huh, that sounds nasty. Does the flickering stuff happen with specific games or just any game you play? If you haven't switched back to windows already, do you think you could capture a small clip of this happening with an external device?
I have similar hardware to you. I haven't seen anything like this with gnome + Wayland but I can try groupinstall KDE on fedora to see if I can hit this too.
Not exactly the same, but here is Firefox doing something similar. The left bar is flickering between desktop wallpaper and the middle bar is a stretch of whatever is on the application and the rest is as it's supposed to be. It seems to be related to the HZ as my video camera cannot capture the flicker, having an effect like what happens when a spinning blade will look like it's not moving.
In games it's usually top right/left square (about 30% width, 20% height) that starts flickering. Either way, there's no need to take time to find a solution, since I'm already transfering things over. The firefox one to my understanding has been documented and common.
I see, do you know if this is specific to Kwin / KDE? I've not seen anything like this so far
