We add "(as superuser)" if the process which owns the window claims to be owned by user 0, i.e. root.
Please reproduce the problem, then do $ xprop|grep _NET_WM_PID and click on the window with the problem. xprop will say something like _NET_WM_PID(CARDINAL) = 1586 And then do marnanel@grantham:~$ ps aunx|grep 1586 (with 1586 replaced by whatever xprop told you). This should say something like 1000 1586 0.0 1.2 188156 52000 ?

When I open GIMP, what I say in the summary above happens. I raised the problem on a GIMP users list. I was told that the same thing does NOT happen when GIMP is installed via flatpak in Fedora. The person who gave me that information also reported a bug to flatpak based on what I'd said, but flatpak closed the bug, claiming that the error isn't a flatpak error, but a Ubuntu error. Hence this report.
