What did Marc do then? (The O_SYNC stuff came from Egbert, > if I'm not mistaken) Right. I slowed things down a bit by forcing the painting of the colour key through the entire wrapped screen, rather than calling an XAA entry directly. This makes this part of Xv support independent of XAA (i.e. Accel/NoAccel), banking, shadowing, etc. Mind you, this slowdown isn't much, given that if the video doesn't move, the colour key isn't repainted. The O_SYNC thing is an orthogonal issue.
