On the ST/STE you can set the screen address at any time, and the shifter will load it during the following VBL. I assumed that the Videl did the same, but apparently it does not. This was the real source of my problems, I called Vsetscreen as soon as the frame was processed, and then waited for the VBL. If I switch this around my original code works perfectly fine, even when using Vsync(). I'll use the _frclock-method instead though, it feels a bit safer.
Thanks for you invaluable help guys, it solved a problem that I had postponed fixing for weeks :)

What's the anti-troll code?
That's your personal code to be able to add comments and messages on the dhs.nu site.
Don't have a code or forgot it? Fix it here.
