Don't commit same buffer multiple times
In Qt we call flush() when we think the window might need to be
updated. It is also possible to trigger a flush while painting.
Two fixes:
1) If there are attempted flushes between beginPaint() and endPaint,
queue them up, and do them in endPaint().
2) Make sure we only commit the buffer once: after that the
compositor owns the buffer, and it can repaint on its own.
