- Most likely, the video board that you have is not fully compatible with
- Apple's guidelines in "Designing Cards and Drivers". We have had
- similar symptoms on older Supermac boards.
-
- As far as I know, there is no fix. We did find, however, that running
- our older Supermac board at 1 bit depth solved the problem (thats the
- easy answer; the better answer is to get a new video board).
