gm_battledesert has a fucked up sun

Hey there, I’m having an issue with the map gm_battledesert

When staring near the sun, a huge strobing black box shows up and when staring directly at the sun the box becomes even bigger and strobes even faster. It’s a real pain in the ass because the only way to play the map is to face the other way and just not look in the direction of the sun.

I would post pictures but I took one with the camera gun, and it looked completely normal as if the map didn’t have the big black box over the sun. So I guess it’s some shitty error on my side that I don’t know how to fix.
