Odd.  The only painting we do ourselves uses Plasma::PanelSvg, which is als=
o=20
used for the panel background as a whole and for the taskbar painting, neit=
her=20
of which seem to produce any glitches.

The cached pixmaps for PanelSvg are pre-filled with Qt::transparent using=20
QPixmap::fill().  QPainter::CompositionMode_Source isn't set before renderi=
ng=20
these to a QPainter, but setting this causes a lot of the panel rendering t=
o=20
be screwed up, because the transparency is effectively ignored.

Incidentally, I can't reproduce the effect you're seeing with the default=20
theme (although I haven't tried with Skype).
