System Information
Windows 10
Nvidia Quadro 600

Blender Version
Broken: 1422f0d

Short description of error
The skin modifier produces different meshes on the default cube.

Exact steps for others to reproduce the error
Trigger the skin modifier to update by doing the same thing I do in the .gif

skin_modifier_bug.blend

Note: this only seems to happen when the edges are orthogonal. When I move one point, the problem doesn't appear on this and connected points.

Can confirm the issue (note that you do not need the subsurf modifier at all, default cube with default skin modifier exhibits the same behavior).

Not sure whether this is bug or known behavior - skin code so not so easy to follow, yet on a very quick glance I do not see anything that could explain that erratic behavior (no threaded parts e.g.)…

What's even stranger adding a new object, for instance a cylinder and changing the number of vertices in the operator panel will trigger the update on the skin modifier.

I can confirm this same bug in 2.83
But I'm marking it as Known Issue, since the report has been open for a long time and this modifier is no longer in active development.
