Wine for instance seems to do randr + wm hints for fullscreen, which actually is working well, but i dont know for certain the details of other apps. If i get some time i might write some test programs doing mode switching in a variety of ways, so we have a testbed we can work with on this.
FYI: For me it is not just games. Some 3D screensavers and amarok plugins behave the sane way. Thanks for responding.
