There may be occurrences when the mouse cursor does not change properly to its resize icon version in Windows 10 over RDP when using SPS.
This is what is to be expected
Instead of that it remains as it is.
This brings a small usability issue
to the table, as you have to be very precise with your mouse in order
to resize a window. This is present in the replay as well.
"Enable cursor shadow" should be disabled on the client.
It seems that changing the mouse pointer size may also affect this behavior. Unfortunately the default pointer size has issues, and enlarged pointers are changing their shape as expected.
