Bug description:
When using pymol[1], the graphics get worse after a second not touching the
program.

This can be overcome with setting Option "Tiling" "false", so I think it is
really related to Tiling.

System environment:
-- chipset: 945G
-- system architecture: 32bit
-- xf86-video-intel: 2.8.1, but it is the same since 2.7.9
-- xserver: 1.6.3.901, but the same in 1.6* at least.
-- mesa: 7.5
-- libdrm: 2.4.12
-- kernel: 2.6.30-gentoo-r4, but also with 2.6.29* and latest git sources
-- Linux distribution: gentoo
-- Machine or mobo model: desktop
-- Display connector: vga

Reproducing steps:
- Install pymol [1]
- fetch 3cwg
- wait a second
