Crash caused by post-effects

[Shadsy]

UPDATE: This crash occurs in the Penumbra: Overture too! I am using the most up-to-date ATI drivers (8.1), which goes along with some of the other error reports. However, instead of having graphical glitches, I'm experiencing a full crash.

I'll attempt reverting to an older version of the drivers (7.9) to see what happens.

EDIT: Yes, it works on older drivers.
