i've gotten a number of reports of this now. so one of the issues was exactly
what i said before: wallpaper rendering is suboptimal.
here's the even better news: it still is! ;) meaning i should be able to juice
more out of it given time...

the svg will suck more than the bitmap until i implement partial blitting in
Plasma::Svg (so, given a dest and source QRect, paint only the dest into the
source) ... it should still be a bit better than it was, though imperfect
yet.
another thing we'll want to do is provide the ability to set the pixmap
caching strategy for Plasma::Svg ... right now it just goes straight to
QPixmapCache which is not optimal in all situations due to being shared.
we're also discussing panel-devel@kde.org how to dynamically resize the
QPixmapCache to keep it properly sized for the needs at runtime.

awesome. you can find us on panel-devel@kde.org and #plasma on irc.
