Description
Describe the bug
It seems that whenever the view model goes from exising to not, the lights for that frame do not get detected. This manifests as a single frame flash whenever this happens.
How do you reproduce the bug?
Have a game with a viewmodel and make that viewmodel no longer exist, see that on the first frame it is not detected, lights do not render.
What is the expected behavior?
The runtime should render lights always.

Research direction
Start by reproducing the transition where a game view model stops existing and observe the first affected frame, using the linked video and runtime logs as references. Trace the runtime's light-detection and rendering flow around that transition; done means lights remain rendered on every frame, including the first frame after view-model disappearance.
