When the tooltip fades away it flickers. Happens in all graphics settings that I tried (Desktop effects). It only happens in Icon view with the detailed tooltips. got an nvidia graphics card with proprietary drivers if that matters
I just realized the same happens in dolphin when I enable tooltips. And I have to correct my first statement: it does not happen in xrender + native/raster, but with all opengl settings.
Thomas, KWin bug?
blur effect, caching, bug #307112 your right arm ;-) @Philipp, run "kcmshell4 kwincompositing", in the 2nd tab, filter for "blur", click the config button and untick the only checkbox. Please report whether that worked and/or mark this bug as dupe of "307112" Also, as we recently learned the kcfg transition caused a bug that caps the blur strength in the config GUI. To get back the default value, run kwriteconfig --file kwinrc --group EffectBlur --key BlurRadius 12 qdbus org.kde.kwin /KWin reconfigureEffect blur qdbus org.kde.kwin /KWin reconfigure
Unchecking "save intermediate rendering results" did the trick! It was checked by default, I think. Thanks for your help Thomas Will mark it as a duplicate as you suggested
