Changing accent colour freezes dock and app switcher
Dear all,
this has existed since updgrading my 15" MBP (2016) to Big Sur and it has persisted through a macOS reinstall, Safe Mode, SMC and PVRAM reset through Apple Support phone assistance.
This is what is happening: go to System Preferences > General > change the accent colour.
The pointer will start misbehaving (that is disappearing sometimes), Cmd-Tab shortcut will stop responding, the Dock (which I keep on auto-hide mode) will not react to the pointer going to the bottom part of the screen. This happens both with the internal trackpad and the Magic Trackpad 2.
Reproducible after a Mac reboot.
The only solution I have found to this is to go to Terminal and type "killall Dock". This will give me back full control. Still, I do not think this is a good behaviour from macOS.
It does not seem to be caused by a specific app.
Thank you
MacBook Pro 15″, macOS 11.3
