Hi,
I'm facing the same problem with nouveau driver but I'm not sure if it is 
driver problem or kde problem. I can't reproduce this at will. With nouveau 
this occurs much often than with nv driver, at least it seems to me. I usually 
get some messages in ~/.xsession-errors:
QPainter::begin: Widget painting can only begin as a result of a paintEvent
QPainter::translate: Painter not active
QPainter::setClipRect: Painter not active
QPainter::hasClipping: Painter not active
QPainter::setPen: Painter not active
QPainter::setBrush: Painter not active
QPainter::drawRects: Painter not active
QPainter::hasClipping: Painter not active
QPainter::setPen: Painter not active
QPainter::setBrush: Painter not active
QPainter::drawRects: Painter not active
QPainter::hasClipping: Painter not active
