When I turn projectors on I get glitches, please help.

[legacy-Shooter_GOD]

I have noticed these strange black glitches around characters, and so I messed around in the settings and found out that it was projectors. I like what the game looks like when its on, but there are weird lines and shapes all over the ground around the characters. Does anyone know how to fix this problem?:cry:
