How to get rid of unwanted zigzag effect on edges? Due to the Solidify Modifier the mesh appears deformed on certain areas. To fix that, I added the Edge Split Modifier, but around the edges in Solid view, appears an unwanted zigzag effect when zoomed-in/out. How can I fix it?

If any body know a solution to this problem, please help.
Does this sort of shift around as you rotate in the viewport?

This looks like a clipping issue. Go into your View tab on the right and muck with the Start and End values under "Clip."
