This solution from mousezero in https://bugs.launchpad.net/elementaryos/+bug/1622060 worked for me. You can also install/use a different cursor theme as long as you change it in both places. The problem seems specific to the Elementary cursor theme rather than a larger problem with the desktop environment.
1. In a terminal type
sudo update-alternatives --config x-cursor-theme
2. Select the number for
/usr/share/icons/Adwaita/cursor.theme
3. install "dconf Editor"
sudo apt-get update
sudo apt-get install dconf-editor
4. in the editor go to
org -> gnome -> desktop -> interface
5. change the entries for
cursor-size = 24
cursor-theme = Adwaita
6. restart your computer
