Description Philipp 2014-05-12 20:47:36 UTC

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?

Comment 3 Thomas Lübking 2014-05-17 18:26:55 UTC

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
