Stereoscopic SBS is anaglyphic Trying to render an image with 2.76 and cycles in SBS (Squeezed Frame) or line-interleaved still renders that anaglyphic red/blue thing in the viewport. (To be more clear, I'm talking about the F12-render and the result in the image editor.) The result should be in real colors. What am I doing wrong?

Only when I save, it saves a image_L.jpg and an image_R.jpg. Those are in real colors but not line-interleaved nor side by sidy squeezed.
You can turn off anaglyphic view by pressing the icon at the bottom row (looks like a pair of glasses? with red/green lenses).

To save as one image, select "Save As Image". When deciding file name, you have a panel at the left, this is where you select the format of the output. The window in the rendering panel doesn't seem to do anything useful.
