            Status: UNCONFIRMED

When switching virtual desktops with main Kadu window opened and 
focused, plasma panel displays graphical glitches as long as Kadu window 
is opened. Don't know if any other applications also cause this bug.

How to reproduce:
- open main Kadu window (contact list) and click on it to gain focus

- now switch virtual desktop 3-4 times(e.g. via pager)
- graphical artifacts appear on plasma panel (or even huge parts of the 
panel disappear), sometimes it affects plasmoids on desktop

Expected behaviour:
- no graphical problems should occur

This bug happens on both of my distro's installed (Arch and Kubuntu) so 
i suppose it is not packaging issue.
