Acid trip shader bug

[Dzwiedz24]

Guys, you gotta see this. From time to time, shaders in the game go mental, both in normal MP and WZ/DMZ. Basically, instead of normal colors there's random neon acid trip - after I verify the game files, it goes away... for some time, but tends to ♥♥♥♥ back up for no reason.
Here are shaders/textures glitching on Zarqwa MP map: https://clips.twitch.tv/JollyAthleticEchidnaDogFace-zUC9_QNGqVOOHxmF
And here are they glitching in the sunken village in DMZ:

What is going on here?! I updated the drivers yesterday, didn't help.
