Operating system: elementaryOS 0.4.1

Short description of error
This is similar to T62115.
When you look through the camera and have Stereoscopy enabled, all the extra drawing items, that are useful in "normal" 3d viewport, are still visible in Camera View:
- Convergence Plane
- Convergence Plane Alpha overlay
- Volume (3D frustrum Volume)
- The Lens Angle widget, only that it is not being drawn in the right position.
This makes it really hard to tell what's going on.
In case of the convergence plane, the alpha overlay makes wireframe objects invisible.
The Lens Angle widget is a problem in general, I think.
While it is super useful when in perspective view, it makes no sense to draw it on top of the camera outline when looking through the camera. It is impossible to use when in camera view, and when the camera is selected it leads to flickering of the outline. Actually it flickers even more when the camera is not selected. While I would argue to not draw that widget at all when in camera view, it should at least be drawn in the correct position, if it has to be drawn.
Exact steps for others to reproduce the error
This is what the camera looks like when Stereocopy is enabled.
Note that there is actually a Bezier Circle beside the Cube, it is invisible though due to the Convergence Plane alpha overlay.
Here's a blendfile demostrating the issue.
