while translating interface to my language I tested
Blender quite hard by doing things that normal user
wouldn't do, because they are kinda like useless. But
they reveal few tiny bugs.
Behold!

Create 'monkey' (or any complicated mesh), exit edit
mode, in object (F7) mode enable Wire, enable Bounds.
Ensure that you in solid (or shaded, but not in wire)
draw mode and choose boundary display type Cone or
Cylinder or Sphere, now wire object has funny
distortions.
