Unfortunately, no, that line can not be added back in. When that line is in place, the backend attempts to process queued events before it is finished processing the current event. It was leading to segfaults in some cases. processEvents should not be called in the middle of processing an event. I tested the responsiveness of panning and zooming with and without that call to processEvents, on Linux and windows and it looked fine. Maybe its an issue related to a specific Qt version on windows. Things looked fine for me with Qt-4.5/PyQt-4.5 on 64bit Vista.
