This is a big bug from Microsoft with 24H2 update. It is same for my HP Spectre 360.
How we can solve this problem? Awaiting urgent reply from Microsoft team.
When you start the laptop, this problem happens all the time. When you restart there is no problem.
The screen scale is changing, that is why the mouse pointer is also becomes to big, althoug it still shows 200%.
When you change screen scale for example from 200% to 175% and come back again to 200%, it solves the problem. But it occurs again, when you shut down the computer and start again.
Microsoft team, please let us know, how to solve the problem.
