Hello,
Yes this is a known issue for the community. It is related with the scalability in RDP (not only native, but also other RDP client softwares) after the Windows 10 Creators update.
The issue is fixed with:
- If you are using a high resolution monitor or big screen, and Local computer graphics are scaled over 100% (125%, 150%) you can reduce to 100%, then reboot and connect to RDP again, now the pointer should work
- Changing the text selection symbol in the remote computer to a larger version in order to enable the "draw" graphic capability for large pointers: Go to Mouse Properties, Pointers, select Text Select and Browse for one of the larger versions, e.g. "beam_im.cur" or mouse properties > pointers tab and selecting the scheme named 'Windows Black (system scheme)'.
