There is a log entry
19.10.2022 00:26:19:037 systemd Failed to start Xdg Desktop Portal For KDE.
right after boot. Then, only when playing games that use Vulkan in some way or another, after some play time, the system freezes. The freeze happens specifically like this:
- Everything freezes except the cursor and the sound
- Then, all of my screens turn black for 2 seconds.
- After that, the image comes back, but everything is still frozen and not clickable (cursor and sound do still work)
The log entry that most likely corresponds to this freeze/dump goes like this:
Process 1186 (xdg-desktop-por) of user 963 dumped core.
