Unfortunately, none of the above helped. I played with a monitor resolution - but it's all useless. For example, in the World of Warcraft or Left 4 Dead, there has never been such a problem.
Can confirm that this is still an issue, only when I use my MacBook Pro with the external monitor I just bought. The Cursor Size fix works, but I don't love that I have to do that. I like having a tiny cursor, lol.
