Graphical glitch with letters upon changing resolution

Check in the source and see if antialiasing has been coded into it, and see if it's set to be enabled by default. If so, change it.

Indeed, from the readme that comes with the client, it is stated that anti-aliasing is added as a mod. But I have no clue on how to remove it or even how it was coded/added :/

Ok, problem solved. The cursor bug I described and the letters glitch occured because of anti aliasing. To remove it, just remove the line with the anti aliasing boxes in the config.xml.

Alright if that fixed it then it sounds like AA is defaultly enabled :p
