Is this the case even with the off-by-one error in the bitblt code fixed? In the 2.4 kernel, I got rid of all artifacts by fixing the off-by-one error.

You mean this code? I see (w-1) and (h-1) in there.



if ( xdir < 0 ) { sx += w-1; dx += w-1; }
if ( ydir < 0 ) { sy += h-1; dy += h-1; }


Yes, that's the code, and it's correct.
