I'm completely baffled as to why Synergy has a fixed window size that takes up almost the entire screen. On a retina mac that's a tremendous amount of wasted space. But what confuses me even more is not even why, but how you did it? I seriously cannot find a window toolkit that makes non-resizable windows. I take that back. Pardon the snark, but I don't care how, but I really don't care why. Join the 1980s (or better yet come forward a few decades!) in application window design...
