I'm experiencing the same issue, with the same hardware.
I tried different graphics settings. The corruption exists only when the
"shader detail" ("Détails de l'image" in french) is set to "low" or "mid". When
set on "high" or "very high", there is no problem. All other settings doesn't
change anything.

Note that when the character is in the sunlight, then the flashlight have less
incidence (less blinking textures).

I have also a Radeon HD 5870 (AMD CYPRESS), and there is no such problem with
this card (same software config).
