Just starting kdiff3 from git mergetool.

Looks like this: https://pasteboard.co/nt2Di75NJiDW.png

Happens if I remove ~/.config/kdiff3rc all the same.

I have created Fedora bug for this issue and see something quite similar:

https://bugzilla.redhat.com/show_bug.cgi?id=2386547

But I think that is already described in bug #499772. I find it quite annoying and had to downgrade to previous kdiff3 version, but later found --noauto or omitting --auto parameter helps to me.

At least on my computer, it is reliably triggered when the window were last time maximized.
