First thought I have is that the ARC drawing routine uses 4096 steps to represent a circle. Larger radii will probably hit the size that rounding can impact things.

Thanks for the hint!
Is it possible to get better results with the non- "_P" routines (using ARC instead of ARC_P)?
(sorry, but i don't have examples using ARC, LINE, etc)
