I am not sure if it really is a bug... it prevents the view from blocking the program by limiting its drawing-time.
If in that time, nothing can be drawn on the surface, nothing is displayed... or am I missunderstanding that one?
See you

The time limit is only if the view is moving, turning, scaling, etc... A:M does as much of a redraw as it can in the time increment chosen.
Once the view has stopped changing A:M should take as much time as needed to complete the screen.
