- Open lid
- Lock screen shows
- Screen fades to black as it realises there's an external monitor
- Finally unlock, windows are all bunched up on the internal display
- Everything becomes unresponsive, maybe even another fade to black
- A minute after initially opening the lid, suddenly all the windows pop back into place
I have no idea if this is improved on M1 machines, but it's frustrating enough on my Intel 16" that I've just pushed all the auto-lock timeouts to excessively large durations.
