Since I upgraded debian to version 13, so for some months now, GIMP dysfunctions, by clicks "in the void". So gimp uses many floating windows, and clicking the OK button typically clicks on the image layer below - without the wanted effect of course. I would like qubes users to test that out and tell me - to understand if it is a gimp bug, an xfce one or a qubes one.
thank you, best, Bernhard
