Metacity should respond correctly to the screen changes; they are reported through the Xinerama extension. I did just notice a bug when using the old xrandr options where the screen size would be set incorrectly on rotation. Either use new xrandr options or update the server. I'm trying to make the gnome background do something sensible; it's a pain. Fixing the screen size GUI and other screen size setting bits needs work at this point. > Opengl performance is the same, using the legacy driver.

Yes, but it all relies on moving to the new memory manager. > Intel EXA acceleration is very slow compared to XAA, and I can often > notice some artifacts when windows are resized (using kwin 3.5.6). > Using a compositing manager (beryl 0.2.0, compiz 0.3.6) the > performance are still slow, compared to XAA. 1.9.94 was sync'ing the hardware after every operation. Not so good for performance. Current git might be a bit better. EXA could use a lot of love at this point. -- keith.packard@intel.com
