hi, check ceiling and floor mesh is proper having two faces and both cover walls end to end. i think there some gap between them and that leaking skylight inside room.
let me know if this the issue and solved.

Hi there,

I apologize for the inconvenience this issue has caused. Aside from what @visualplus has said, you can also try turning off this option in Preferences and see if the flickering is still evident. Thank you.
