Right now nothing works well, so about everything is a step in the good direction. There's also another new way which might be a good option aswell next to the scissor one and that is to use the new GLX_EXT_texture_from_pixmap extension. Using it wine windows can be uploaded 'for free' to opengl. We can then do our opengl rendering on top of this texture. It is just a wild idea but perhaps it is usefull.
