Garry's Mod screen problem

Hello. Everything about my problem is notifyable on video in link. I thought it was something about motion blur but changing it (enabled / disabled) change nothing. It happens only with this particular game. I have no idea what created this problem, it was running good for about half year now. None of “solved” threads around steam / facepunch forums didn’t helped me. I’d really appreciate any kind of help, thank you.
P.S.: Video is not placed in any promotional purpose, it’s only evidence of problem.


Go into Sandbox, post processing, and make sure none of them are checked. Look in effects too.

It worked, thank you so much for help :slight_smile:
