New, advanced window manager (WM) for Flashback
This is more like meta question, but in same time may be seen as bug and feature request probably. Metacity doesn't have hardware compositing, have some issue in video games, full screen games/application, stutters when CPU utilized at 100% and such. Compiz is another story and new 0.9.X version doesn't even packaged in many distros because it's somewhat experimental and unstable (boost, GCC regressions and build failures, etc).
The question is: can we port and integrate GNOME Flashaback from Metacity and Compiz on let's say Mutter? Is it real and doable and if so, how hard is it? Thanks in advance.
