[Bug]: OCIO DisplayViewTransform Output is Incorrect (RV 2024.1.0)

[jonahjnewton]

What happened?

Pull request #414 fixed an error with using OCIO v2's DisplayViewTransform node.

Using the colorspace below which uses this DisplayViewTransform (also used in issue #403), alongside the ACES 1.0 SDR Rec 709 Display Transform, the output looks correct and there is no longer an error. However as I load a second sequence of media and swap back to the original sequence, the image looks darker than it's supposed to. Moving the sequence onto different monitors also has some strange effects.

- !<ColorSpace>
    name: ACES 1.0 SDR-video (Rec709)
    aliases: [aces_to_rec709_rec1886_ala]
    family: Clipped View Output
    description: |
      ACES ACES 1.0 SDR-video for Rec.709 broadcast monitor with Rec.1886 gamma (2.4)
    isdata: false
    categories: [ file-io ]
    encoding: sdr-video
    from_scene_reference: !<GroupTransform>
      children:
        - !<DisplayViewTransform> {src: ACES2065-1, display: "Rec.1886 Rec.709 - Display", view: "ACES 1.0 - SDR Video"}
        - !<RangeTransform> {min_in_value: 0., min_out_value: 0., max_in_value: 1., max_out_value: 1.}

Any help with this would be very appreciated.

Cheers
Jonah

Extra information

Steps to replicate:

1. Add ColorSpace in bug description into OCIO config.
2. Load this ColorSpace in RV.
3. Load a second sequence of media
4. Swap between the sequences of media in the Session manager

Hi @jonahjnewton !
I cannot contribute anything to this issue, just want to recommend to you to obfuscate your environment variables a bit more. The SHOTGUN_DESKTOP_CURRENT_USER contains a session key that could give me (temporary) access to your Flow Production Tracking. There also seems to be a permanent API key SG_API_KEY.
Hope that helps.
