Short description of error

Blender crashes when a plane is displayed in wireframe, if the view is aligned with its side (*e.g.* when looking at a horizontal plane from a numpad 1 or 3 Ortho view).

Exact steps for others to reproduce the error

  • Open Blender

Then, in any order:

  • Add a Plane mesh
  • hit Z and select "Wireframe"
  • hit numpad 1 or numpad 3

Event Timeline

Nicola De Mitri (nicolasap) renamed this task from Crash every time 2 meshes are displayed in wireframe from Front or Right Ortho mode to Orthographic wireframe view of a plane mesh causes crash.

Further info:

  1. doesn't happen in Edit Mode
  1. doesn't happen with a generic planar face, provided it belongs to a more complex mesh (the default cube alone doesn't cause a crash)
  1. but it doesn't have to be a plane primitive either: removing 4 vertices from the default cube causes the crash. Moving a vertex (locked Z) from a default plane still causes the crash
Bastien Montagne (mont29) triaged this task as Normal priority.

Cannot confirm that here on Debian testing, with embedded intel GPU (HD4600)…

@Clément Foucault (fclem) three different reports with different GPUs and OSs though, there must be something fishy ;)
