I have had a lot of instability on Hyprland recently, with a lot of crashes. For some reason, I have this specifically with certain apps such as calibre and nautilus.

The crash log:

[CRITICAL] 
==========================================================================================
ASSERTION FAILED! 

Attempted to duplicate CWLSurface ownership!

at: line 158 in WLSurface.cpp

My system-wide Hyprland configuration
And my userspace config

If anyone could help me find out if this a bug or a misuse on my side that would be awesome.
