Colorful rectangles are added incorrectly by breeze-gtk theme

[Thomas Stieler]

When using gtk-breeze theme in Kubuntu 22.04, is see additional colorful rectanges in Gimp, when I switch to Gnome's Adwaita theme, they disappear.

I attached two sceenshots, so the difference (beside of the different themes itself) should be clearly visible...

Unfortuately it's not only the gtk-breeze theme that breaks Gimp's UI, the problems also appears with Adwaita theme, but much less prominent.

So maybe gtk-breeze triggers the issue more intensivly, but the issue seems to be more general and GTK related, because in the meantime I noticed, that other GTK programs are also slightly effected.
