Description
There is some funny behavior with fixed_orientation_mobject and the way the stroke is rendered relative to the camera orientation, see these two screenshots:


I don't think this should block merging this though. We can just open an issue and document the behavior to be fixed eventually.

Research direction
Start by reproducing the two reported screenshots with fixed_orientation_mobject in the OpenGL renderer while changing the camera orientation. Compare how the stroke is rendered in each view and trace the fixed_orientation_mobject handling. Done means the stroke no longer changes unexpectedly with camera orientation.
