Nvidia Quadro 600
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
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.
