Dolphin Emulator Bluetooth Passthrough not working on Bazzite Steam Deck LCD

I installed Dolphin via EmuDeck today. I setup the correct udev rule and enabled Bluetooth Passthrough in Dolphin. On SteamOS it worked but on Bazzite it is stuck on a black screen when starting a game. Have I to do something else?

This is a question for EmuDeck/Steam ROM Manager. I can confirm Dolphin works properly on my setup running Bazzite.
