Broken: Blender - from a long time ago
Worked: not working till now
Short description of error
I do not know if it is a bug or it should work in this way, but it is annoying- when you do mirroring some mesh by scaling by -1 (or any minus value) in edit mode along one of the axis the normals of faces and verts are inverted. It is seeing of course in backface culling mode or when display normals are on.
Exact steps for others to reproduce the error
open blender in default settings, go into edit mode of the cube, select all verts, faced or edges, scale by -1 along any axis, switch on backface culling option in properties panel (N)
