Yeah, so there is no way for me to know for certain, but what I'm guessing is that the game has hardcoded resolution constraints and 1366x768 isn't viable because it's not a true 16:9 resolution (it's an approximation that comes close to 16:9, but it's more like 16.008:9). Trying changing your resolution to 1280x720 or if your laptop supports it try setting it to 1920x1080 and then try and my guess is it will work.
