--- Comment #2 from Henri Verbeet hverbeet@gmail.com 2009-08-24 07:08:11 --- I'm pretty sure this is a bug in the driver, so bugs.freedesktop.org is a more appropriate place to report this. The problem is probably something like compressed textures not being properly initialized when they're specified through glTexImage2D().
