Expected Behavior

The two numbers displayed in the Script Log should be different.

Current Behavior

The two numbers displayed in the Script Log are equal.

Steps to Reproduce

1. Turn Studio Mode on
2. Turn Duplicate Scene on
3. Change the horizontal position of an item in the scene that’s currently displayed in the Program view
4. Run the script
5. Open the Script Log

Anything else we should know?

Python script to run:

import obspython as obs

def script_update(settings):
    scene_sources = [obs.obs_frontend_get_current_scene(), obs.obs_frontend_get_current_preview_scene()]
    result = []
    for scene_src in scene_sources:
        items = obs.obs_scene_enum_items(obs.obs_scene_from_source(scene_src))
        for item in items:
            pos = obs.vec2()
            obs.obs_sceneitem_get_pos(item, pos)
            result.append(pos.x)
        obs.sceneitem_list_release(items)
    obs.source_list_release(scene_sources)
    print(*result)

Reproduce the issue with the provided Python script while Studio Mode and Duplicate Scene are enabled, then trace the obs_frontend_get_current_scene and obs_frontend_get_current_preview_scene entry points. Compare their results while editing the Program view; done means the two scene positions reported in the Script Log reflect the distinct Program and Preview scenes.
