@seb_degraff Huh, interesting. Would you mind if I debug a bit? At the very least it would be great if you can grab some system files, I can give you instructions of what to get (though it'll be a bit large, maybe 2GB with all the recoveryOS stuff).

This case is particularly interesting because either you have an older System RecoveryOS than your boot firmware (which would be a first), or both System and Paired RecoveryOS are Sonoma but somehow one works and the other one doesn't, which might help us pinpoint exactly what causes the screen snafu.

Happy to do this over a videocall or something like that if you prefer.
