My display is 1680x1050, connected via DVI-D, Ubuntu version is 15.10 64-bit. I do a fresh Ubuntu install and install and run glmark2. The horse spins smoothly. I set "System settings -> Displays -> Rotation" to "Counterclockwise", rotate my display and run glmark2 again. The horse totally stutters. When the rotation is "Counterclockwise" other OpenGL applications will even freeze.
