My cursor has gone weird?

So I had this problem since the I bought the game as many others, where it wouldn't run in fullscreen, but it would run in windowed borderless, with extremely low fps. I thought it was my laptop not being good enough (though I meet all the requirements) and played with very low fps for about 40 hrs, till I found a dragon and the fight was impossible without being able to move properly.

So I decided to investigate and found out that the game wasn't using my nvidia card but the intel card. Searching on the internet I found posts that helped me fix this and now the game runs using the nvidia and I have no more lag :D I am extremely happy, except for one thing.

Since I did this my cursor has broken :/ I dunno what happened but it lost all texture. Now it's black and white and you can see the pixels one by one! 
It's nothing major but it annoys me, I can't tell if I am close enough to something to click/loot and it just plainly looks bad.

Anybody has any idea why this has happened? :/ anyone had the same problem?
Here is a pic of what my cursor looks like now. This is only in the game, it's fine outside btw. And I've already tried setting the graphics higher to see if it would change..
