Strange tear in textures

The tear looks like this:

or this:

If it’s not visible watch it in 1080p fullscreen to see the texture tearing.

If you can’t see it here is a pic I created with unity to show the tear: Imgur: The magic of the Internet
It’s very similar to a screen tear but only visible on the left an right wall.

It’s not vsync, the lighting nor overlapping uv meshes. It happens both in unity 2018 lts and 2019 lts. I’ve tested everything I can think of, gone through all google pages with all the search terms I can think of. Asked in all unity chats I could find, done everything everyone told me to do/check, nobody could find what the problem is.
I can’t release my game with this bug and I’m at the end of the road with this.

I’m pretty desperate if nobody here can help, I’ll have to rebuild the game from scratch in another engine, which I really really don’t want to do since that will cost me many month of development.

Are you referring to the coloured stripes not aligning within textures? That is the only thing I can see, even at 1080p.

If it is that, it looks like you have Filter Mode set to Point in the Texture Import Settings. Change it to either of the other settings.

Aniso Level could also be contributing as you are viewing the textures at an angle. Try turning that up (and making sure Anisotropic Textures is enabled in the Quality settings).
