any updates on this? I have the same issue; after sleep/restart, the pointer is reset to a giant size (as big as the taskbar). what I do is go into settings-accessibility-mouse and change the size (it's already the smallest, but the config is ignored, so I have to make it big and then small again).
this is happening on a clean install/freshly updated W11 on a surface pro 11
EDIT: I can easily reproduce the issue if I go into the old mouse settings menu and change anything in there. the options for pointers are all large or extra large and if any is selected, the thumbnails for every pointer case looks weird.
EDIT 2: I think the mouse is resetting to it's huge size even after I touch the screen (with fingers, or pen)
EDIT 3: so if I go to settings - accessibility - mouse pointer and change the size to max (which is ridiculous) and then I touch the screen, it gets as big as 1/3 of the screen :))
EDIT 4: POSSIBLE WORKAROUND I played around with Settings - System - Display - Scale; the default was 200%, changed it around and then back to 200%, now if I touch the screen, pointer stays the same size
