The Windows 10 style start menu does not fill the screen.
Configuration/Use fullscreen menu is set to On.
Previous version worked fine and the problem occurred when I updated to the latest (without changing any settings).
Tried fiddling with settings (which looked OK) and restarting the PC but the problem remains.
If Configuration/Use fullscreen menu is set to Off, the start menu can be dragged to full screen but it snaps back to be smaller than full screen.
Using Windows 11 22H2, Build 22621.1413, on Surface Pro 8.
