Apple Studio Display XDR with M3 Pro

I'm glad Apple updated the Studio Display to offer a version with HDR and 120Hz. The previous Studio Display has accurate colors and great resolution, but the upgrades are very welcome.

I use a Macbook Pro with the M3 Pro, which supports 120Hz with the monitor, even though their specs page could be clearer about it - only the base M2 and M3 limit it to 60Hz.

Things get more tricky when using two monitors - I'd like to use my previous Studio Display as a secondary screen. Daisy chaining, as promised by Apple, doesn't work, only the XDR display turns on. I assume this is a bandwidth limitation of TB4.

Plugging in the Studio Display to another port on the macbook doesn't make things much better - this time USB devices work, but the screen stays dark. The only way I made both displays work was to connect the Studio Display first, then the XDR display - both work, but the XDR display is now limited to 60Hz.

Changing the display preset in the Displays pane in System Settings crashes and reboots my macbook. I then have to replug both displays in the correct order again.

Sound only works through one monitor. I think there exists software to make it use both, but don't want to bother.

When the original Studio Display came out, there were also some issues - e.g. the camera was just terrible. After 1-2 software updates, I didn't run into any issues anymore and it was as stable as any other monitor since.

I hope Apple fixes the initialization of both displays during boot and when plugging the XDR display first. Those two bugs are quite annoying.
