Linux broken world phong

[username00112233]

Searched for duplicates.
Tried on x64 and none.
Can't test without addon, as one is needed to show the effect at all. (I think)

Details

I tried the same thing on the windows version, there were no issues.
This is probably related to ToGL.

Linux:

Steps to reproduce

Map used was: gm_genesis
Materials are from: https://steamcommunity.com/sharedfiles/filedetails/?id=3034391550

Additional things

The Real CSM mod is also broken on linux. (I'm not sure if it deserves it's own issue, because it's probably the same reason (ToGL), but it is a GMod problem, not the mods problem. Because it is only broken on Linux.)

If you need me to test something or check additional things, i will do that.
