I had this same issue. In my case my MAIN display was the extended display. You have a checkbox in display settings 'Make this my main display'. Make sure it is checked for your laptop's display and NOT for your extended display. The issue seems to be resolved for me when I made this change.
So, in short you just have to make sure your main display is your laptop's display and NOT the extended one.
My setup looks like this - I have one extended display on top of my windows laptop.
I hope this helps! Thanks!
