When I use the "Share Screen" feature, I lose control of my Mouse in Full Screen Mode

I have 2 Macs, a MacBook Pro 13" and a Mac Mini, and I use the "Share Screen" feature quite a bit. I love this feature and it has been working very well. But lately, I would say the last month, I lose the control of my Mouse when I go to Full Screen. The mouse works well if I don't go to Full Screen, but after I do, it doesn't work at all on the Remote Mac. It works fine all the time on my local Mac, in the other Desktops.

Does anybody have that same issue?
