I'm on a Mac (10.13.6). Same issue. Including not able to left click on trackpad/touchpad within inventory.
Im using OSX 10.9.4 with 16 GB ram 2.6 GHZ i7, GeForce GT 650M. Ridiculous drop in framerate, sometimes almost unplayable. Game also freezes every 10 minutes about half a second. This is a major issue.
