Short description of error
There is 3D graphic artifacts when using weight paint mode in wireframe viewport shading !
There is no artifacts on blender 2.82

Exact steps for others to reproduce the error
. Open this simple blend file weight_paint_wireframe_graphic_artifact_283_ce7.blend
. Uncheck Edit > Lock object modes
. In pose mode Select the bone "Bone" or other one and with shift select the monkey
. With Ctrl Tab switch to weight paint mode

If so, I'm reproducing the same artifacts as you and it's probably linked to #74243.

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 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.
