Thanks for the report, but there is no bug here, just select Objects' Display "Draw All Edges" option if you want them all (Blender optimizes out 'flat' edges by default).

Thanks for the response @mont29!

Maybe the description wasn't as precise as I hoped.
Have you checked the wireframe display of the selected edges in Editmode?

Gah, sorry…

Well, in default '3' Right side I’d say this is to be expected (since it’s on the 'hidden' side), but same behavior on Left PoV indeed seems buggy.

Probably yet another issue due to the fact we do not use Zbuffer in Wire draw mode?

I don't think there's a bug here. In edit mode we don't cull edges according to flatness, while derived meshes do get that. See for instance a plane subdivided a few times.

@Psy-Fi You are making same mistake as I did, we are talking about Edit mode here, not Object one. ;)

@STEP-ANI-MOTION Thanks for the report, but unfortunately we can't do much here, we do not use ZBuffer in Wire draw mode to gain speed, it does have some drawbacks (like this one), but we consider it known limitations currently, not bugs.
