Odd.  The only painting we do ourselves uses Plasma::PanelSvg, which is also 
used for the panel background as a whole and for the taskbar painting, neither 
of which seem to produce any glitches.

The cached pixmaps for PanelSvg are pre-filled with Qt::transparent using 
QPixmap::fill().  QPainter::CompositionMode_Source isn't set before rendering 
these to a QPainter, but setting this causes a lot of the panel rendering to 
be screwed up, because the transparency is effectively ignored.

Incidentally, I can't reproduce the effect you're seeing with the default 
theme (although I haven't tried with Skype).
