I have a blender file which works perfectly if I choose ortho mode, but if I press 5 and turn to perspective mode it would show like this.
In the perspective mode, I can only view it from a long distance that means if I try to slide the wheel to zoom in, it will occurs the occlusion error.
NOTE: I checked this in my other blender files. They all behaved normally, just this file has the problem.
Could anyone give a hand or some suggestions to fix it?
