Output repaint uses a pair of fence syncs to profile GPU execution by retrieving their timestamps once signalled. While the end timestamp can be rather inaccurate in some cases (drivers reusing sync objects from previous command buffers), the begin timestamp is never correct because fence syncs are signalled on command buffer completion. Get rid of the begin fence sync and use the EXT_disjoint_timer_query extension to measure the actual repaint duration and extrapolate the begin timestamp from the end one.
