Menu bar unresponsive
The macOS Big Sur menu bar becomes unresponsive from time to time.
Specifically the "Apple Menu" and the "App Menus" in the left part.
The menubar apps and the Notification Centre in the right part work fine.
I'm on a M1 MacBook Pro, with an Apple Keyboard, a Magic Mouse and an LG 32" external display connected.
The menu seems to freeze when the first notifications come in, but I'm not sure about that.
The login screen als has an issue: a beige colored section appears at the left, about an inch wide, full height.
MacBook Pro 13″, macOS 11.1
