Random distortions colors Ubuntu 16.04 x64 GeForce GT 755M

I’ve installed Nvidia driver 370.28 from ppa and faced with a problem that image quality is very poor.
I’ve tried older driver versions but the result is the same. There is no such problem with Nouveau drivers.
Laptop: Lenovo y510p

Graphical adapter: 01:00.0 VGA compatible controller: NVIDIA Corporation GK107M [GeForce GT 755M] (rev a1)

Found out that xorg-devel package was missed. Installed it.
Adjusted graphic setup to Maximum Performance and now the image quality is very good.
It is confusing to me.
