Caused by 10131a6f62

Short description of error
Wireframe overlay is broken when subdivision surface modifier is set with Optimal Display enabled, and certain geometry changes (Decimate modifier or Dual Mesh via Geometry Nodes) happen after that.

(Tried tuning off GPU Subdivision and factory settings, but this still happens.)

Exact steps for others to reproduce the error

From startup file, enable wireframe overlay
Add subdivision surface modifier to the cube. (Setting it level 4 makes it easier to see the issue) Make sure that Optimal Display is enabled (default)
Add Decimate modifier or Dual Mesh via Geometry Nodes
