Worked: version 2.93.6

Short description of error
Non-mesh objects (e.g. camera, armature, empty) with Viewport Display set to 'In Front' aren't always visible after toggling 'Show Overlay'.

Exact steps for others to reproduce the error
Open attached blend file:

1. open any new window (e.g. F4, Preferences) --must be seperate window-- and simply close it
2. without clicking in 3D view, toggle 'Show Overlays'. The non-mesh objects don't (re)appear until clicking in 3D view

Notes:

• this only happens with some samples set in 'Viewport Anti-Aliasing' (under Viewport in Preferences)
• instead of opening and closing a window, other actions can cause the issue, but is less predictable/reproducible
• seems to occur more often in heavier files (e.g. on armature of fully rigged character)
