Need help updating Rostselmash SK-4 combine for FS22

[elbrus1986]

Hey, I'm currently updating the SK-4 Combine by KBD, for now just for myself, but if I get all bugs fixed I will contact the author to ask if he wants to have the files.
So far I got all the scripting bugs fixed, also the bug that it did not work with Courseplay is fixed.
But now I run into a problem where I do not have the slightest clue what is causing it, that is the weird graphics glitch.
Here is a picture of it, does anyone have a clue what that is?

You can see the graphics glitch better in this video:

When I hit F5 for the debug rendering, the second "mode" shows these 2 white lines, and they are exactly the spot where the graphics glitches come from:

I am glad I am not the only one with this issue. I love this mod but the black line glitch issue is rather annoying.
