I do wonder if WM_MOUSEMOVE has priority over WM_PAINT so that if the mouse is moving a lot, that could affect the latency of WM_PAINT.
I think we used to artificially bump keyboard and mouse messages over posted messages to stop posted messages from affecting the latency of mouse messages. Either way, WM_PAINT comes second last just before WM_TIMER. See http://msdn.microsoft.com/en-gb/library/windows/desktop/ms644936.aspx
