How to reproduce:
1) Open the attached project.
2) Run in editor or build using 2018.2.0a5+
3) The red strip renders a portion of the cubemap from a camera that is identical to the main camera. Notice that the perspective within the rendered (red) portion is incorrect.
4) Run the same project in any 2018.2 release through 2018.2.0a4. The correct behavior is observed in these releases.

Expected Result: Cubemap and conversion to Equirectangular textures should match the rendering camera's transform.
Actual Result: Incorrect rotations appear in the cubemap and equirectangular textures.

Regression first introduced: 2018.2.0a5
Reproducibile with- 2018.2.0a5+
Not reproducible with- 2018.2.0a1, 2018.2.0a4
