If you are talking about moving windows onscreen (blitting), then Dano 
works out just the same as R5. It still distorts. The only possible 
reason for this being less evident, is the app_server taking smaller 
offset steps for each blit: therefore a move feels smoother.

I am a simple observer here after all.
