The problems seems to be that we try to initialize the QPainter object

Yep and that's why I erased all use of qp_ private member in
"QLPainter.C" (start() and end() do nothing).
Hmm, I would have suspected that exactly this change is what causes the
error.
I am not sure because QLPainter is only painting onto a pixmap. The only
painting onto an X11 device is in QWorkArea::paintEvent.
I thought even painting into a pixmap should only be done in a
paintEvent(). The pixmap is located on the server side after all...
I don't think so... or maybe I don't understand what you mean by "server
side". The pixmap is located in QWorkArea, painting on it is done
throught QLPainter and that could be done anytime. But I guess there
could be some buffering optimisation in QLPainter.
