SUMMARY:
Recently both in Kde neon and nixOS when I move/resize a x11 window a few times
or once, it hangs my entier system.
I didn't experience this issue 2 weeks ago.
I sadly cannot get any log as my system hangs.

STEPS TO REPRODUCE
1. Open a x11 window (I use SDL3 for that)
2. Move/resize the window once or a few time


OBSERVED RESULT
-System hangs require force shutdown.
-Or extreme lag if you can close

EXPECTED RESULT
No system hang after interacting with the window
