Not 100% sure, but can confirm there is something going on that seems weird to my eyes as well.

@Clément Foucault (fclem): there seems to be a difference in edge highlighting between Display modifier in Editmode ON/OFF. Adjust Edit cage to modifier result resumes to "better" edge highlighting if turned ON...

Or maybe @Jeroen Bakker (jbakker) also knows?

I am sadly to report that with today build (22/05/2019) the bug is still visible. i don't know if that fix is included in that build.

D4907 fixed a different issue, not related to this bug report.

Clément Foucault (fclem) lowered the priority of this task from 50 to Low.May 30 2019, 6:23 PM

This is due to the edit mode antialiasing not using the MSAA buffer. I would like to fix this but this requires a relatively massive refactor of how we draw overlays.
Basically we should draw all overlays as one draw engine instead of multiple ones.

So I will consider this low priority.

Note that with the overlay refactor this issue is much less noticeable but still here.

This should have been fixed by the overlay refactor.

Sorry I was too quick. It still happens. But I would say it's a known issue for now as it's not something I will be fixing soon.
