Happens everytime I reboot or start the machine.
No idea what causes this.
I have the following startup apps:
conky
ulauncher
gear lever (flatpak)

Comment 14 Volker Braun 2026-04-27 09:22:55 UTC 
For me xorg-x11-server-Xwayland-24.1.10-1.fc43.x86_64.rpm is also crashing

After booting Xwayland-24.1.10 I cannot open x windows, e.g. running "xclock" in a terminal hangs and does not open a window. Just in case anybody else notices that symptom.

Downgrading to the previous xorg-x11-server-Xwayland-24.1.8-2.fc43.x86_64.rpm does not crash any more, but is not really desirable as I understand there were some CVEs.

This is https://gitlab.freedesktop.org/xorg/xserver/-/work_items/1886 fixed with https://gitlab.freedesktop.org/xorg/xserver/-/merge_requests/2190 upstream.

Will release xwayland-24.1.11 to address that issue (and others).
