When we activate the Deferred technical preview feature and then exit the game and leave it in the background, after returning, the world's lighting breaks completely and becomes extremely bright, the night becomes extremely dark.

Even closing and opening the world the bug remains, you need to close the game and restart to fix the problem.

I'm using the Vanilla RTX texture, but the bug is occurring with any texture that uses PBR.

I had to reduce the resolution of the video because it was too heavy to send.
