Topic: [HELP] Wrong resolution
First off, I think that it's pretty shitty that you have to sign up to report a bug.
I run Linux with dual monitors, and the starting resolution of Teeworlds appears to include the sum of both monitors' resolutions, but this was a problem for me as my main monitor is on the right, so it started there and right half of the game didn't show, and I couldn't move my mouse a third of the way. I'd fix this.
