For additional information about hardware or used effects have a look at https://bugs.kde.org/show_bug.cgi?id=303331 Is that what you actually see in the large screenshot or did you gray out regions for privacy reasons? Also please cross-check with a) the xrender backend. b) the blur effect disabled Oops, I expected the XRender question and tested it already but I forgot to mention that it has no effect :-) I only grayed out the desktop background to shrink the snapshot to an uploadable size. Disabling the blur effect only fixed the blurred clock issue (aka point 3). Ok, so at the end of the day the major issue is that a frame of the switcher reamains on screen?! a) does the swoitcher type matter? b) which plasma theme (if it's from kde-look, ideally with a link to the exact one - there's a bazillion "air-dings" ;-) > Ok, so at the end of the day the major issue is that a frame of the switcher reamains on screen?! Well and that the task bar becomes invisible. > a) does the swoitcher type matter? I tried to changed it but I always get the box switch with (big) thumbnails?!? > b) which plasma theme (if it's from kde-look, ideally with a link to the exact one - there's a bazillion "air-dings" ;-) Standard "Slim Glow" I have exactly the same issue here with Kubuntu 12.04.1 and KDE 4.9.1. A frame of the switcher remains on screen after releasing the alt+tab keys. If I use the window switcher on a desktop without windows, I also get the partly vanished panel Andre described. Moreover, I cannot change the type of switcher. I am stuck with "window preview". The only other switchers that work are the 3d window gallery and 3d stacked windows, but even then the window preview switcher remains in the background (see attached screenshot).

looks like the BoxSwitch effect is actually configured as tabbox!
kwriteconfig --file kwinrc --group Effect-BoxSwitch --key TabBox false
kwriteconfig --file kwinrc --group Effect-BoxSwitch --key TabBoxAlternative false
qdbus org.kde.kwin /KWin reconfigure
qdbus org.kde.kwin /KWin reconfigureEffect boxswitch
@Martin:
- primaryTabBox = conf.readEntry("TabBox", false);
- secondaryTabBox = conf.readEntry("TabBoxAlternative", false);
+ primaryTabBox = false;
+ secondaryTabBox = false;
yesno?

Git commit c09cf68d7f2487e257ab7bf095ff9dca81ae6802 by Thomas Lübking. Committed on 03/10/2012 at 18:57. Pushed by luebking into branch 'KDE/4.9'. Hardcode TabBox setting in boxswitch effect false Boxswitch is activated as tabbox, possibly due to a downstream issue This results in multiple effects being assigned to the tabbox and no GUI way for the user to fix this. Since the BoxSwitch effects nowadays only exists as sidearm for coverswitch, the tabbox setting is now hardcoded and disabled in the effect, making it completely impossible to accidentally use it as tabbox.
