Strange squares flickering on the screen running the game

So I've been working on this FPS project and recently these strange squared started to appear. Those seem to appear only in the seams between the models and it happens in builds and when ran in Unity. Squares are not appearing in the 3D viewport.

The problem seems to be very similar to this (sadly there is no solution):

Any help would be appreciated.
