Wow thanks, this is an issue that got reported a lot in the last time! Do you know if it's safe to assume that desktop Linux systems use Xinerama these days? Otherwise we'd need a fallback for that case...

Also, is it easy to change the global screenWidth()/screenHeight() functions instead, and just keep using those for the window size? So that you can open a fullscreen window with screenWidth x screenHeight pixels and rely on having no (possibly blurry) stretching at all.
