Re: compiz refresh problems with QT apps
We discussed this at the X Developers Conference. glXWaitX isn't even guaranteed to be sufficient because it only causes the GL to wait for X rendering from the current client (i.e. Compiz), and not necessarily other clients (i.e. the one that caused the Damage event). It should be okay for now, but what's really needed is interaction between X's Damage extension and the GL_ARB_sync extension.
