Strange artifacts in builds

Hello! I'm creating a 2d game. It works fine in the editor, however as soon as I create a build and play it from there I get theese strange artifacts.

All UI elements display correctly. So do all particle systems. On the right side of the screen I don't see any of the sprites. The artifacts you see on the boat-thingy are visible on all textures at that x-pos. I don't know what else to say.

(The green thing is due to using a very low res texture, however half of that spritesis also not visible)

I tried to lower the quality settings. That didn't change anything other then make the streaks/lines in the middle wider and with more space inbetween them. So could it perhaps be an AA issue? Or am I just being an idiot and doing something wrong when loading the sprites?

Thanks in advance!

EDIT: Nothing on the right side of the screen is rendered, all on the left side of the screen is rendered correctly and then it's that part in the middle which gives those lines on the sprites.

It also only seems to be affecting sprites.
