This is a WTF problem

[Moerges]

Hi there!

The same problem bugs me since a month or so; I can usually work around it by switching to fullscreen and then back to normal/double size. That's no big deal, but still irritating.
My taskbar is at the bottom - it always has been there. So fixing the bug by moving the taskbar away from the top won't work for me. Any other ideas?

Thx in advance.
