Screenshot of Windows10 pointer preferences under Virtualbox

I am using Plasma 5.26.0 with a 4k screen and 200% scaling.
The scaling of XWayland apps work well now, thanks!
One problem I still have is with Virtualbox, with a Windows 10 guest and mouse integration.
The Windows10 pointer is twice too big.
I don't have this problem with KDE/X11 or Gnome/Wayland, so I reckon it is a KDE/Wayland bug.

STEPS TO REPRODUCE
1. Use Plasma 5.26.0 with a 4k screen and 200% scaling
2. Launch Virtualbox with a Windows10 guest and mouse integration
3. Look at the size of the pointer

OBSERVED RESULT
The pointer is twice too big.

EXPECTED RESULT
The pointer should have a normal size.
