Hey Joris,
Us two must be the most unlucky and error-prone guys on this list when it comes to CGX!!!

I think there is an ENV variable you can set which allows you to reserve some (1MB) of the CV64/3d card's onboard memory for sprites (or something) or you can have it disabled so the full 4MB can be used for storing pages... You may need to change that variable...
I had my WB screen and also IBrowse doing the same as yours for some time... I think I just cut the resolution down to 800x600 instead of the 1024x768 or whatever it was that I tried for a while... Also if you use IBrowse, use the "tabs" instead of opening extra windows if you can.. seems to be abit quicker for me (40MHz '040) or maybe it's just because it doesn't have to try and redraw an entire screen when you change windows from front-to-back.
I also found it (screen gfx glitches) was due to IBrowse chewing up all my 32MB of FAST RAM after about half an hour of use... I bought an additional 32MB and have never run out of memory since (even after 6-8 hours without a reset, which was the only way I could get my RAM back before!)
