Short description of error
When multi-view is active, I can't see effect Stereoscopy in the camera view.

Exact steps for others to reproduce the error
Based on a (as simple as possible) attached .blend file with minimum amount of steps

  1. Open Blender.
  2. (default view), go to Scene panel and active (Checked) Views.
  3. In the 3D View, Change to camera view (press 0 in Number. pad).Captura de pantalla de 2015-06-09 18:58:15.png

Most likely an openGL driver issue, can you please:

  • Try to tweak OGL settings in UserPreferences, System tab.
  • Attach here the report generated by Help -> System Info.
  • Try to start in software OpenGL mode (use the blender-softwaregl distributed with official blender, will be slow, but will show whether this is a driver issue or not).

The answer is really simple and this is not a bug.
Go to user preferences-> system and set window draw method from automatic to triple buffer.

Enjoy.

thank you, and i'm sorry for work extra :(

We do need to add info in the manual that the feature is only available in triple buffered mode though.

No worries, it's not something that you can know without looking at the code (answer is "simple" from coding, not user perspective).

@dfelinto, can you make sure the manual explicitly mentions that viewing multiview is only supported in triple buffering?

I know, it's because automatic window method will not use triple buffering for open source (Gallium) or software renderers. But you can't know that as a user, all the more reasons to add it in the manual.
