Mouse movement is 'sticky' in OS X El Capitan

[cainram]

I am running Minetest version 0.4.13 on OS X 10.11.3 El Capitan on a MacBook Pro Retina 15-inch Mid 2015 with a 2.5 GHz Intel Core i7 and 16 GB RAM. The graphics chip is listed as Intel Iris Pro 1536 MB.

The issue is that the mouse-look or aiming is sticky, as in the mouse will move the point of view as normal for a half second and then there is no response for the next half second. It is as though the mouse is being switched on and off rapidly. There is no issue with movement. It is smooth and normal when walking around with the wasd keys. The mouse also moves normally when in the inventory screen. The cursor movement is smooth and normal.

I do not have this issue with other games. I have the issue even when using a wired mouse or a bluetooth mouse or trackpad.

I have not had this issue in Ubuntu, Lubuntu or Windows.

I have the issue whether I am playing in single player mode or when connecting to a server on my local network. I have a dedicated server running on my local network and can play with no issues on a Windows desktop and a Linux desktop at the same time as my Mac. The MacBook Pro is the only computer I experience this issue with. It renders the game unplayable, which is a shame because it RULES.

If anyone has anything for me to try, I'm all ears.


EDIT---------!!!

Fixed it. Couldn't find this before for some reason...
