Priority: P2: Important
Affects Version/s: 5.15.2
Fix Version/s: None
This looks like a regression in 5.15.2.
Scene3D can be configured to OnDemand rendering and it works fine for 3D entities,
but any other items are rendered at every frame.
1. create Scene3D and set RenderSettings.OnDemand (see attached empty scene)
2. run qmlscene ondemand-scene3d-updates.qml by RenderDoc
3. Check fps and/or capture frame to see which items are rendered
