what version of mesa are you using?  what is your max desktop size?
If it's texture pressure, you can try reducing your max desktop size
by adding a virtual line to the display subsection of the screen
section of your display.  something like:
Virtual 1400 1050
or
Virtual 1024 768
depending on what size screen you have.
