Comment 11 for bug 223238

This is not an Intel graphics specific problem as suggested in the thread linked to by the previous comment as I am seeing it with an 8800 GTS both with and without Compiz.

The GUIMark benchmark at http://www.craftymind.com/factory/guimark/GUIMark_HTML4.html really illustrates this problem clearly. Under Windows XP I get 10 fps, but in Ubuntu 8.04 I get less than one frame per second.
