Public bug reported:

I installed correct nvidia 390 for my card.But it seems less efficient
than using Intel integrated graphic card.Window movement and web page
scrolling aren't smooth.That's vary annoying.If I use Intel
card,everything is smooth.

nvidia-smi says 'Volatile GPU-Util' is not zero.But is it really using
nvidia for rendering?
