Doe it look like this?

If so, I'm reproducing the same artifacts as you and it's probably linked to T74243.

The developers are having a hard time reproducing the issue and so they're having a hard time fixing it. The only fix at the moment is to use Blender 2.82a (as you said), disable anti-aliasing in user preferences, or revert the Workbench refactor (At least that's the believed cause for the issue. Currently the developers have been unable to pin-point the exact change that caused the issue because the Workbench refactor was a large patch).

@Alaska (Alaska) Exactly this look like your screenshot.
Thank you to confirm with me this same strange graphic artifacts.
Good luck for the developers to solve this bug.
