Graphic glitch on certain bound.

I frequently see a graphical glitch on certain types of bound.

Most often i see this happening when the bound are inside a cave or building. Many times i can't actually see the bound but i can see the glitch as i'm approaching their location.

It looks like a kind of flickering shadow of straight lines that flash across the screen at random intervals.

It seems to happen the most with the headbutting bound and also the flying Haxans but it occasionally happens on other bound too.

I attach 2 videos where you can see the effect i'm talking about. The first is a quick clip in real time which i then repeat and freeze the frame where the glitch happens.

The glitch was only one frame long.

The second video is a collection of the same kind of glitches.

When i think about it, I only clearly remember seeing these glitches in desert realms, i will update this post as i play further and see if i spot them in other realms too or not.

I'm assuming you're already aware of this issue, but if you do want me to list my pc specs let me know.
