I upgraded last night and sadly, it's not working for me
It detects the monitors, and seems to load them just fine. I can even see the mouse when I move it on to those screens, and if I connect it while my lockscreen is up, I can even see the background for the lockscreen stuck on the monitors once I log in.
However, I can't see any windows, or when I go into overview I don't see any motion. It almost seems like an issue with the config on Gnome. Needless to say, this is with switching the session to Xorg.
