This line smells wrong. The chances of ptr already being a QPaintDevice just seems really low, since there's almost nothing in Qt that returns a QPaintDevice-casted pointer. If it's really a QWidget, I can easily see QPainter::begin() checking for the "am I being painted?" bit at the wrong offset, and seeing it set.

Since painter->begin(ptr) doesn't have a cast in it, I don't think that would compile cleanly given a void*, would it?
