Version: (using KDE 4.0.98) Installed from: Ubuntu Packages OS: Linux 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 http://img165.imageshack.us/img165/4765/plasmazy0.png - 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 http://img372.imageshack.us/img372/2286/plasma2hv2.png http://img231.imageshack.us/img231/4097/plasma3st6.png 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.
x.org driver problem; upstream issue.
