Ok, fair enough.
I've tried with metacity, and you're right it's damn slow.
But the display is also corrupted. All the pixel on the right of the
(non-rotated) screen are garbled, I'd say on the last fifth of the
display.
I took a screenshot, but on the screenshot everything is allright. So
the corruption happens only on-screen.
