Some guides missing from viewport overlays menu

Hi, sometimes I don’t get 3D cursor and other options in the Overlays menu. I was beating my head against the wall but it’s probably a bug, right?

MacOS 10.14.6 with Blender 2.80.

For sure, there is no obvious justification to that lost.
It could be a limitation of display abilities on machines with poor OpenGL support.
But it would not be intermittent.

That is probably a bug. I am not able to reproduce it.

I’m seeing a lot of these quirks (and not in old projects, these are all new.projects). What would be the best Course of action, just resetting prefs?

And yes, this is a 2015 5k iMac with AMD card, so probably a poor OpenGL support. It is intermittent.
