Short description of error
I can see through the mesh in edit mode when I move further from the object. When I zoom in it starts to draw properly.
Exact steps for others to reproduce the error
Add a Plane. Add a solidify modifier. Apply. Add a subsurface modifier, set it by 6 and apply.
Zoom in and out of the mesh and you can see how the drawing of the mesh changes.
