%%%--- Operating System, Graphics card ---
MACOS10.8.4
NVIDIA GeForce GT 650M 512 Mo

- Blender version with error, and version that worked ---

2.68a

- Short description of error ---

Mesh looks completely messed up when switching to wireframe with "draw all edges" enabled. It seems to happen only with an armature-bound mesh. Sometimes (?), maximizing the view (shift+spacebar) fixes the mesh drawing.

- Steps for others to reproduce the error (preferably based on attached .blend file) ---

Select the geometry and check "draw all edges" in object tab
Switch to wireframe display
May or may not appear broken to you, sounds like a graphics card thing

%%%My mistake, it does not depend on "draw all edges" being on or off, rather on "wire".%%%

%%%Looks fine here. mesh is also valid/

Can you check if this happens on a different computer?
Can you see if this is related to the VBO user preference?
Could you upload an image of what you see?%%%

%%%Confirmed, on OS X with NVidia GT 650M. Only happens when VBO is enabled.

The mesh shows scrambled, like the vertex locations are ok but they are connected randomly. Also, when saving in wireframe mode it opens ok, but when you toggle to solid draw mode and back it shows wrong again.%%%

%%%I look at this for quite a while but couldn't understand what's going on here. Even with the OpenGL state and VBO contents identical it can still render correct in one case and incorrect in the other. I guess there's a particular order of operations that triggers a bug in the OpenGL driver, but I haven't found yet what that is.%%%

I can't redo this anymore on the same computer I tested this before, but now with OS X 10.10. Both Blender 2.68a and 2.76 work fine now, so I'm going to assume this was a graphics driver bug that is now fixed.
