Bugs/Issues: everything is fine, have some weird issues in RT though, not GEM related but really annoying (GEM 0.90 + RT = freeze/crash/watchdog, PDP 0.12.3 + RT + GLX window = freeze/crash/watchdog).
I think a similar thing happens on OSX using -rt as well. The GUI locks up when the CPU loads gets high although GEM continues to render to the window. I've always thought it had to do with GEM monopolizing the video hardware and not giving other processes a chance to draw, and do other UI events. The problem seemed to stem from OSX's GUI being an OpenGL process itself, but looks like that might not be the case.
well in my case it just can't render one single frame, as soon as the window is created (either gem or pdp_glx), pd is either gone/watchdoging or in worst cases linux freezes.
so i'm afraid it has to deal with the gl libs and the fglrx driver...
