On startup I'm getting a "We reached more than 3 frames in flight. That's too many. Did you forget to call cp_frame_end_submission()?" error despite cp_frame_end_submission() being called when needed. Nothing is rendered in the 1 frame that does go through. Is there something I'm missing that would cause cp_frame_end_submission to not register?

For RoomAnchors there's different mesh classifications for mesh anchors, but only walls and floors are supported by geometries() function. So given this how can I get information about other mesh classifications?
