X Window System error on Trisquel (Ubuntu 22.04 LTS)

[Michael Terry]

I was just looking into this error too (on Fedora 41 for me).

It goes away if I used GSK_RENDERER=ngl instead of vulkan, or I rebuild my GNOME app with org.gnome.Sdk//47 instead of 48, or just switch to Wayland.

Some bug in gtk 4.18 maybe?
