Small fix that makes overal UI (including dragging spliiters) much, much faster.

Flushing messages meant that for every event, UI was reaccomodating everything. This is relly slow.
Messages will have to happen sometime later, during iteration most likely.
I still can't fix the overall code editor slowness on Mesa+Radeon, I suspect it's a driver issue.
