Hi everyone,

I'm trying out KDE Plasma on EndeavourOS (Arch-based). My previous distro was Linux Mint, and games ran super well. Now on here, I'm noticing games are a bit choppy, so I looked into ways to improve performance, including disabling the Compositor. However, when the compositor is off, randomly a game will freeze the entire desktop. Audio still plays, but I cannot enter a new tty and cannot move the mouse or do anything on the keyboard. The only way I found to recover here is manually power off the machine.

I'm running this on a laptop with Nvidia drivers, and I run in hybrid mode.

Here's the output of `inxi -Fxz`:

I wish I had more information, but I'm not sure where to look for logs when the system freezes, or how to further debug what might be causing it. As a reminder, issue does not happen on Mint.

Here are my compositor settings:

Code: Select all

[x] Enable on startup
[x] Allow applications to block compositing
Scale Method: Accurate
Latency: Force lowest latency (may cause dropped frames)
Tearing prevention ("vsync"): Automatic
Keep window thumbnails: Always


A few more things to note:
- I can reliably reproduce it. The desktop will freeze usually after a few minutes of playing. This is regardless of whether "Allow applications to block compositing" is enabled or not.
- I can move the mouse and disconnec/reconnect bluetooth devices while it's in the frozen state.
- However, the keyboard doesn't work, which prevents me from entering the tty, exiting the application, or doing anything.
