I believe I just had this happen, though there was a reboot and kernel

gnome-shell was also topping out CPU.

Thanks Michal. The diff looks perfectly clean and exactly what I would
expect in that no part of the system has changed that would fool mutter
into doing the wrong thing. So it's just that mutter's done the wrong
thing... somehow. And that wrong thing is not visible in the above text

wakes up (although the lockscreen blurred background is shown black, but

just works. Again,
