WinUAE internally creates following bitmap when in filter-modes:
...........................
........xxxxxxxx........
........xxxxxxxx........
. = empty space.
x = "real" display that only needs filtering. Filtering whole internal display would be 3x slower..
It is needed for size/position adjustments or display would "wrap around" if WinUAE's display window is bigger than emulated window. Of course it is possible to use some copy blits to create same effect but it would only cause even more slow downs...
HQ-filter don't support this kind of display layout. All other filters support this very common feature.
