Version:           4.6 (using KDE 4.6.3) 
OS:                Linux

Hi devs,

this one seems to be quite tricky and is somewhat hard to explain, but I will try - I've assigned this issue to KDE because it influences the whole desktop somehow.

Ok, I have Kontact running and the Tray Icon enabled for KMail to be always shown. Now Kontact sits minimized in my tray.
Sometimes when I open it up, Kontact restores but I can't click anything - instead whenever I click somewhere on the Screen Kontact minimizes again - but that's not all, when I click again somewhere on the screen it restores again. After several clicks the system seems to catch up again so I can at least work in other applications - but there is another problem: It's not possible to move the windows or use one of the window operations (minimize...). An Alt+F2 followed by "kwin --replace" usually fixes that.
But after that, the Applications in the Plasma Task Bar are not clickable - at least until I sometimes clicked wildly on it after what it starts to react again.

So I really don't know what's causing it but it seems some weired combination of Kontact, the Systray, KWin and Plasma which is leading to that effect. Maybe it may also be an X error but that's all suspisions.




Reproducible: Sometimes




KDE packages come from the openSUSE Tumbleweed repository but I experienced the behaviour also with the packages from default 11.4 and the Factory repository.
