Weird rendering issues

[IntoxicatedCookie]

Hello

 

I just downloaded Forge on my client to add this awesome SecurityCraft mod.

So i can put cameras and other kinds of security in my brand new villa im building.

 

I already made a part of the villa before ive put Forge on it and same for the mod.

But i noticed, when i walk around or rotate my view it does this weird thing that makes it unclear for a second.

 

(I cant capture it on a screenshot since its too fast)

 

Its like it has to load or render things, not sure.

 

Let me know ASAP, maybe its just something stupid like something i have to reconfigure.
