Tivimate 5.0 Beta discussion - finally adding PiP on Nvidia Shield?

Has anyone tried the new 5.0 Beta APK floating around the Telegram group? The changelog says 'Improved hardware decoding for Picture-in-Picture on Android TV 11+', which sounds like Alex finally cracked the PiP issue on the Nvidia Shield. I'm at work and can't test it yet. Does it actually work without crashing the player?
