Issues with large window size

Soo I have run into an issue that is quite weird, when using TwbT and resizing my window above somewhere around 2052~ (roughly) horizontal resolution then the text starts acting weirdly. It goes from this: http://puu.sh/fG1RR/cace3ae44d.png to this http://puu.sh/fG1Ub/b054ab4614.png when it passes a certain width. I have been unable to find a way to prevent it and while it's playable it's quite annoying that the text is not as clear but rather weirdly pixelated.
