Graphics corruption Picasso96

@Flashlab:

If you have CyberGraphX, you could try with that and see if you get graphical errors then too.

If you dont have the commercial v4, you can download the free v3 here. Just be sure to completely remove Picasso96 before installing.

@Flashlab:

It is more likely that you are pushing the graphics-card over its limits than the monitor. The max of that card in 8-bit should be around 1280x1024@60Hz, in 16-bit around 1024x768@75Hz and in 24-bit around 800x600@60Hz.

So, try different and lower modes if you havent and see if it makes a difference.

@Flashlab:

What Amiga are you using the card in? If you have the possibility, you should try it in a different Amiga and preferrably an Amiga with genuine Zorro-slots - like an A2000, A3000 or A4000.

A friend of mine had similar issues with his CV64 (distorted text) because of Zorro-bus issues. The previous owner of his A4000 had fitted it with a Buster 7 chip (a that old Buster is not supposed to be in an A4000, only A3000). This problem vanished when he got a proper Buster chip. So the Zorro-bus evidently worked, but not flawless and that made his CV64 output corrupted text for some reason. So I was thinking that it could perhaps be a Zorro-bus issue for you too.

Btw, regarding setting the horizontal frequency for a mode to 31.5KHz in Picasso96Mode doesnt automatically render you a usable mode. For example - if you would try to run a 800x600 screenmode in a horizontal frequency of 31.5KHz, that would result in a vertical frequency of probably below 50Hz which your monitor most likely cant display. It also depends on the timings - blanking-interval size for example.
