From before...,in my Mac Intel Iris GPU, Wire frame and the edge will not be displayed in the Geometry Window.
And,no-affect for other user, I suggest to add options "Draw Offset" into Preference > Misc > Workaround.
I've investigated the problem.
By changing the parameters of the wings_render.erl, Wireframe and Edge display successfully.
Please look at the following illustrations for details.
