Short description of error
When i adjust to display an interlaced result in the viewport, then the viewport shows me the interlaced result.
When i render an interlaced stereoscopic image with interlaced, then the image editor displays the anaglyph result, and not the stereoscopic result.
Saving out works then as expected. It saves the interlaced image. So the interlaced image is there. It is just not displayed in the image editor.
Exact steps for others to reproduce the error
In the Output settings activate Stereoscopy.
In the Output panel in the Views subtab activate Stereo 3D and set the method to Interlace.
Render the image. It displays as anaglyph in the image editor.
Save the image. The saved image will be interlaced.
