Version: unspecified (using KDE 4.6.0) OS: Linux Like stated in bug 264372, since KDE SC 4.6.0 the panel has repaint issues when using together with yakuake and having panel on top of the screen. This was not the case with 4.5.5 As a workaround you can set "Windows may cover panel" (translated from German). Reproducible: Always Steps to Reproduce: move panel to top start yakuake invoke with F12 (or whatever hotkey you selected) close with F12 Actual Results: artefacts from yakuake remain on panel Expected Results: no artefacts, panel visible like before using yakuake As a workaround you can set "Windows may cover panel" (translated from German).
