I found an issue today; either a new bug or not.
My laptop is an Asus Zenbook Flip S running Windows 11 22H2 22621.3007
I very, very rarely use it in flipped mode. Yesterday, I did just that, making use of the touchscreen to do some onscreen drawing. I don't like the tablet mode so have told Windows not to use it if I flip the laptop. I flipped it back before shutting down.
Today, the Windows elements of the taskbar were half offscreen -- shifted downwards. After a restart or two, and working standalone and with an external monitor fitted (the mode I was in when I flipped the laptop) I was unable to resolve the problem by changing screen resolutions and the like, and eventually decided to switch off Start11 to see if it was implicated.
Long story short: the problem resolved when I switched off "Let Start 11 enhance the taskbar" and allowed the explorer restart.
Toggling the setting again (and restarting explorer) didn't induce the problem, but I found that changing the setting of "Taskbar touch mode detection" from "Automatic mode (recommended)" to "Force not touch mode device" brought the problem back.
I'd guess that Automatic mode is slightly broken?
