ID 474613 - From SBP: Camera animation on 3D environment often causes panels to be rendered incorrectly by Flix

Problem summary
Camera moves in a 3D storyboard environment are likely to be incorrectly rendered in Flix.

Customer reported version
Flix 6.3.5

Steps to reproduce

Note: This is an intermittent issue which depends largely on the camera move and placement of the layers in the 3D environment.

1) In SBP, create one panel that's 1 frame long, with at least 3 layers including background, then copy it 6 times. The idea is to have 7 panels in the scene, with a common background and subject.

2) Enable 3D for the scene and move at least one of the layers in the foreground.

3) Add a camera keyframe at the start and one at the end of the scene. The screenshots below show (first keyframe on the left, second keyframe on the right) the values combination that reproduced the bug more consistently. Other values for the camera may or may not reproduce the same issue.

4) ​Double check that the camera animation isn't revealing any canvas area, and if the camera movement bring it outside the artwork area, extend the artwork.

5) Save this as an .sboard file and import it to Flix.​

Expected behaviour
All panels are correctly framed, appearing in Flix just like they appear in SBP.

Actual behaviour
Some panels show the canvas behind the artwork and are framed weird.
