Arch Linux

Description:
Something scary happened between GIMP 2.10.8 and 2.10.10, which now happens to crash Xorg.

Running:
Xorg 1.20.4
Nvidia 418.74 with Prime configuration

GIMP can be started normally and new image can be created/opened.
As soon as the cursor moves onto the canvas, Xorg gets aborted and you are catapulted back to login manager.
This doesn't happen with Wayland, it happens both on GNOME and Plasma.

This bug is not present in 2.10.8, however GIMP's GitLab doesn't have opened issue for any similar problem.

The nuisance is, there are no logs present neither for GIMP, nor Xorg.
Xorgs gets internally aborted and ends after SIGABRT without saying much.

Journalctl at the moment of moving cursor:

[/code]

Steps to reproduce:
Happens always, try to open some image and edit it.

Now, blacklisting gimp in pacman.conf is *not* the proper solution for this.
Does anyone have similar problem, so I can open issue for GIMP's developers?
