GIMP Window Changes Size on Any Action

[Jeremy_Ray]

What user profile would I have to delete?

I tried switching back to single window mode, and that didn't solve the problem either.

Perhaps the problem is a setting in KDE, but I wouldn't know where to look.

Or the problem with the window reducing could be unrelated. I remember seeing this before, on a different OS install. I can't remember how I fixed it. I seem to remember it going away on its own, but that probably isn't how it actually happened.
