I'm experiencing some issues. The mouse pointer is very jumpy as soon as I move it to the drawing pane (but fine anywhere else in the user interface, i.e. menu bars etc). Navigation in any camera mode is also very jumpy. I'm using HD 2017 18.3.2.2 on MacOS Sierra 10.12.1 (new MacBook Pro 2016). Anyone else having similar issues? Any solutions? Note: same HD version runs very smoothly on lower specs Mac mini late 2012 with OS X El Capitan 10.11.4
