MacOS 'WindowServer' and 'Roon' process CPU spike

Rebuilding db from scratch on Core, this is from the client MacOS machine.

Music not playing, client just sitting on Overview screen. Ingested albums are updating as expected. Closing and restarting client, CPU begins climbing within a few seconds…

Rebuilding db as I recently dumped Tidal for Qobuz and wanted to purge all the Tidal artwork, etc. I sure wish there was a true db cleanup (remove deleted items and reclaim space) ability with this db.
