Since I switched back from Windows to Arch Linux 6 months ago when I bought an Intel ARC A380 to use the newly released KDE Plasma 6 Wayland, I've been having daily kwin_wayland segmentation faults.

I figured it would be fixed eventually and switched to Hyprland for a few months, but after switching back, re-installing, and switching to my Nvidia RTX 3090 as my primary GPU, it's still happening.

Have you noticed any pattern behind the crash? i.e. when is it more likely to occur?
Comment 5 Vlad Zahorodnii 2024-09-20 12:35:42 UTC 
Do you use night light or anything that's not enabled by default?
