I too can confirm the same issue with any game which runs on a lower resolution than the native resolution
problem is indeed with the intel driver i suppose. because you can work around it once you set the desktop resolution to a lower setting the other scaling options magically appear then all the games can run full screen without black borders with lower resolutions. definitely a driver issue
my setup toshiba satellite p50t-a intel hd 4000 +nvidia 740m
