Bug/Issue Mouse Cursor Misbehavior/Movement Bug Upon Launch

Upon game launch, the mouse cursor immediately moves itself to the upper left-hand corner of my screen and remains there. I'm able to still move the cursor, but it persists to move back to the upper left-hand corner. Cursor speed changes once it leaves the game window when in Windowed Mode - increasing drastically, making it very difficult to then select any option within the game window. I have not gotten past the Character Creation screen due to this bug, sadly, so I cannot confirm it remains a constant problem after this point.

This happens in both full-screen mode and windowed mode.

This occurs on every game launch, even after a full reinstall.

I'm using Mac OSX version 10.11.6 (El Capitan).
I am unable to attempt to reproduce this bug on a Windows 7 OS due to missing hardware requirements.

Do you have a controller plugged in at all? Some controllers are poorly calibrated and will show analog sticks as constantly moving off to the side. I've had to workaround that sort of thing in other games.

Alternatively, are you using a mouse or a trackpad? Do you have any mouse/trackpad accessibility settings turned on?

 

I had a Playstation 3 Duelshock 3 Six-Axis controller plugged in. I hadn't accounted for that being a possible problem - usually I have to press the PS button to get my computer to register the controllers inputs.

I was using a Logitech m305 wireless mouse, I've never personally liked using trackpads.

I unplugged the controller before launching Steam, to be safe, and then opened the game. No mouse movement. =)
I never would of thought my controller being plugged in would cause this kind of thing, never personally ran into this kind of problem in the past.
Thank you for the help. I greatly appreciate it. =)
