Please note that there is an experimental update waiting for you in the icomp forum on which I am still expecting feedback. The suspect is here that the blitter engine of the S3 chip conflicts with the pipleline of the regular VGA engine (not with that of the stream processor which is used for lower resolutions). It would be nice if you could test the experimental chip driver and provide feedback.

@Overmann, If there is a thread about this on the icomp forum, then I suggest the discussion/support continues there.

I installed V3.01of P96 on my A4000 to test it.
Now no glitches are present. At least all glitches i had are gone with my CV64 /3D

And do you use Classic WB, better WB, best WB, OS 3.9, or newer?

First CGX3, then version 4, on plain OS 3.1, on a plain A4000/040.
