Yes, I was talking about double buffering. The WIZ had the issue in the rotation routine, AFAIK. Even games using double buffering had tearing (but only AFTER the rotation - if you disabled the rotation, everything was working fine).
Ok. I don't know which kind of panel WIZ had, but it sounds like it had a panel with its own framebuffer, and the panel's rotation was used. That causes diagonal tearing.
Even that's avoidable with some trickery, though. Nokia N9 actually does that kind of trickery.
Rotation with TILER is different, no such problems there.
