The goal is to sync the pixmap before we start drawing to it, so doing it at glFlush time is too late. -- Alexandre Julliard julliard(a)winehq.org

Is the pixmap updated with the DIB memory, or is the DIB memory updated with the pixmap? In the latter case, it should be fine. Also, I'm not even sure a DIB can have a proper GL context, given that GL rendering by nature is device-dependant (possibly forgoing generic/software rendering, which we don't export). Is there anything which shows this is possible, or should I try to make some tests?

It's supposed to work both ways.

Tests would definitely be a good idea. -- Alexandre Julliard julliard(a)winehq.org
