"Put Display to Sleep" Hot Corner works for a moment then screen turns back on...

I have an M1 Mac Studio connected to a Studio Display and I have assigned all four corners to "Put Display to Sleep". When I move the mouse to any of the corners the screen will sleep but then IMMEDIATELY comes back on. I find I have to do this 3,4,5,6 times before the screen will stay asleep. This happens using a Magic Mouse BUT oddly using a run of the mill Logitech mouse the problem is gone...it's never happened once. I also have an M3 24" iMac with Magic Mouse and this issue has never happened. I know it's a trivial thing but this has been going on for years across different versions of MacOS and it is so irritating. I also had dual Pro Display XDR monitors a one point on this Mac Studio and it was the same situation. It's like the Magic Mouse keep sending info after it has stopped moving and causes the screen to turn back on or something.

Open Activity Monitor and choose the Energy Tab. On the right side of the screen, see if there are any apps that say "Yes" in the Preventing Sleep column. If the app has a disclosure triangle on the left, you may need to open it for more details.

Sounds like the Apple Magic Mouse is picking up finger movement when you let go of it.

Maybe try holding the Apple mouse by the outer edges when you move it to a hot corner.

I checked and there are none ... I also would not think that is the issue because I can swap over to a Logitech mouse and the issue is resolved.

I thought so too but if it were the way I used the mouse that would also be the same when i use my M3 iMac and Magic Mouse. But I tried your suggestion and it still does it. Now I am thinking it's this specific magic mouse. I am gonna swap with my iMac mouse and see if that changes at all. I know this is trivial but it's a function I use constantly when I walk away from my computer.
