Guild Wars 2

Ok, so… 2 days ago i started noticing some strange lag with my ingame cursor.

problem 1. Whenever i move my cursor over to my second screen, the ingame cursor does not dissapear and remains in the game. Its not really an issue, but worth pointing out since it didnt happen before

2. Whenever i hold right click to move the camera, the cursor DOES NOT dissapear as it should be. Not really an issue, but quite annoying, since i like holding right click just to remove the cursor.

3. Whenever i get alot people around me, like in LA or WvW zergs my cursors starts lagging very bad. Even if my framerate is 30+ the cursor gets slow and starts lagging.

I have no idea whats causing this, but i know its gamebreaking for me, because all i do is WvW. But thats impossible with this slow and lagging cursor.

I installed a new graphic driver a few days ago, can that be my problem? I have tried installing a new one after the problem occured, because i thought that might be the problem, but no… It still works like that
