Wireframe is not visible on square planes with 16384 quads (128x128), both in edit and object mode.

Exact steps for others to reproduce the error
Launch blender.

  3. Subdivide the plane until it gets 16384 quads. You may notice that wireframe disappears at this point.
  4. Switch to face select, delete random quad and wireframe will appear.
  5. Fill the hole with new quad and wireframe disappears again., as soon as topology is back to 128x128 quads.
