[Qgis-developer] QgsMapCanvas::paintEvent() too frequent

QgsMapCanvas::paintEvent() is called too frequently on my X11, for example:
- 11 times when mouse enters map canvas (if QGIS does not have focus)
- 10 times when mouse leaves map canvas
- 13 times when minimized QGIS is restored

Does anybody know why and how it could be reduced?
