Possible to change scroll refresh rate to match monitor (e.g. 120Hz, 144Hz)

Its not possible from within Okular.
According to QScroller documentation, there is a global animation timer which 
sets the update rate.
This timer should match the frame rate of the screen, but apparently that 
doesn’t work.
(Maybe you have more than one monitor, or the monitor changes framerate after 
startup, or Qt fails to detect it correctly.)

It surprises me, because they use either line-wise scrolling, which happens 
instantly, or Okular.
If it works in the Kile document preview, that means Kile is better than the 
Okular shell in detecting the framerate.
