Tulga graphic glitches when throwing knives

[Lomendil]

Maybe this can help, I first got those weird images when trying to switch to throwing knives after failling at sneaking in Tulga (Spy quest). No problem when I was staying with the staff. This glitch always come with a 5-10sec total freeze.

Once in the city (Take a walk around the streets), the bug seemed to happen every 15-20 secs.


Note that I never saw it before (playing for a few months).

I just have to stop throwing knives in Tulga, no need to switch to DX7 ...
