I was in the middle of making a plane when this happened
This happened suddenly when I switched from orthographic to perspective view. This only happens in Default view when in perspective view. The model looks fine when anywhere else, like the full 3D view and UV map editing. It also looks likes this when in texture and material view in default layout. I have tried restarting the computer and blender but nothing works. All of my other blender files are normal, but any shape in this certain one looks like in the picture. Please help.
