Public bug reported:
I recently bought a new monitor that shows no banding when looking at
gradients in Windows 8.1 (even after calibration) and under fluxbox but
does in Unity. It's not 16-bit-level-banding but definitively visible
and exaggerated after screen calibration. Not nice when you want to do
graphical work or are anal about display quality like me ;)
