No, this is only related to the new painting scheme in the properpaint branch. Basically what happens is that, when one has consecutively processEvents(Force); processEvents(FitCursor); everything was Ok in the 2.3 world : the screen would be fully redrawn with the first call, and then probably not touched with the second. In the new world, the first call will recompute metrics and ask for full redraw and the second will ask for no redraw. So when the paint event occurs, no painting is done. The patch makes sure that update flags are cumulative. But since this is a big semantic change, I expect collateral effects. JMarc
