Fresh cube mesh was added, and shaped into a rectangular shape. Dark blobs appear to be showing when the mesh is selected in edit mode, zoomed in enough, and with the subdivision view to 2.
When object mode is selected the blobs disappear and the mesh appears normal.
Also, when zooming out enough, the dark blobs begin to disappear.
Is this a graphical glitch, or is this a problem with the mesh itself? The mesh is very new, just pulled faces and extruded 2-3 times. Thanks!
