[Jobbo]

[Edit] Turned out to be a copper setup bug.

I'm investigating a very strange bug in a demo effect where the colors are flickering intermittently.

I've been investigating the code for a while now but I had a thought that maybe the problem is that I'm only doing one wait between copper driven blits.

This had seemed to work fine for me until now.

Does WinUAE actually suffer from this problem, or am I looking in the wrong place again?

I understand that some old hardware will not wait correctly with just one blitter wait but for a demo I was going to ignore that.
