Object Mode shows odd Jitter on Mesh? I am working off of the blender 2.83, I started a render and then stopped it to fix a mesh issue. When I returned to object mode I was greeted with this lovely disconcerting sight.
I have done the basics of turning blender on and off, clearing material caches, changing render modes. turning off layer....ect.
Any help would be appreciated, but please someone tell me my file isn't corrupted 

Thank you.
If there are no mesh issues, overlapping faces etc. and it also appears when creating new faces, try the following:
In 3D Viewport, press N, to open the Sidebar, go to View &gt; Clip Start / End and change the values to e.g. 0.001 and 1000.
Sometimes these issues appear when you have imported an object which is very large or very small in Blender because of different unit systems or similar reasons, and when you are zooming in or out on the object or change the clipping to make it visible this strange behaviour can occur.
Not sure if this is the case with your file, but I get this error every once in a while.
