Got a strange problem with one of my CyberVision 64 4MB cards... Take a look at the picture below.
Those two red "blocks" follow the pointer, and after a while there will be graphics glitches on the Workbench when closing windows and so on.... anyone seen this before?
I have ruled out the daughterboard, buster chip.
Have tried another identical graphics-card in the same machine, and there are no glitches, so this is not software related either.
If i wiggle the card a bit, I can see differences in the graphic disturbances, but only minor changes.
(those horizontal lines are there only because I took a picture with my phone on a MV1438 monitor, CRT)
