OSX - gigantic mouse cursor.

**Describe the issue**
Unfortunately I don't have any logs to provide, but I'll try to explain the problem.

When I start a virtualized OSX guest (Sonoma or Sequoia), after logging in, the mouse cursor on the guest screen is giant.
When I move the mouse cursor out of the guest screen area, it's back to normal.

It seems to be related to the screen resolution (I'm using 2560 x 1440), because when I change the resolution or resize the guest window by dragging from the bottom right corner (first smaller and then back to larger), the mouse cursor returns to normal for a while, but when I move the mouse out of the guest screen and back to the guest screen, the mouse is giant again.

However, when I record a video of this phenomenon, the mouse cursor is normal while watching the video. So I had to take photos to show it.

**Configuration**
* UTM Version: 4.5.4
* macOS Version: Sonoma 14.7.1
* Mac Chip: M2
