Description

Blender Version
Broken : dff7f55cd069 (2.8 HEAD)
Worked : unknown

Short description of error

The Scene strip preview always use the last updated scene - updating the a scene (changing a scene setting) breaks the sequencer preview and makes this scene render instead of the one specified in the Scene Strip.

Exact steps for others to reproduce the error

You can recreate this file from scratch by adding a new scene, and adding a scene strip in the VSE.

  • Tweak scene exposure
  • Change current frame

Extra notes

Surprisingly, the render engine is always the one from the Scene Strip scene, even if another scene is rendered.

More info: For testing changing color management exposure should be enough to trigger the bug, however you also need to change the frame to see the issue.

Also I animated the file, and now I can no longer reproduce the issue with it (the original file still has the bug, obviously):

While --enable-copy-on-write will assert if you try opening this file (P648 if @Sergey Sharybin (sergey) is interested), when re-creating from scratch the error is still there.
