Review request for Calligra and Boudewijn Rempt.
Description
-------
On AMD graphic cards the Krita OpengGL 2 branch shows some flickering. The
problem happens when only a part of the widget is updated e.g. when switching
between menu.
The patch solves that by dropping paint events that update that have an update
rect smaller than the size of the widget. In that case a new update with the
full size of the widget is trigger.
It's somewhat of an ugly hack, but it's the best solution that I could find.
Better suggestions appreciated.
This addresses bug 322808.
