[MC-241298] Failed to get system info for GL Caps: Rendersystem called from wrong thread

Whilst flying in spectator mode in my old world opened to LAN, the log warned "Failed to get system info for GL Caps: java.lang.IllegalStateException: Rendersystem called from wrong thread". I don't know if this is important or how to reproduce this.

Log (abridged, 1.18 Pre-release 1)
