example of the scrolling behaviour
When scrolling fast with the mouse wheel through a document in okular 20.04.0
it is now a very sluggish experience. When using the scrollbar on the other
hand everything is very fast.
I have attached an example video. You can see the jumpiness of the scroll bar,
when using the mouse wheel. Furthermore, the wheel scroll speed is almost
identical through this video. When it comes to the bottom of the document it
slows down a lot. In the second part of the video, I am using the scroll bar.
As you can see, the scrolling is much smoother.
I am using
Okular 20.04.0
Frameworks 5.69.0
Plasma 5.18.4.1
.. on a not so slow pc (i7-4790K, with Geforce GTX 970 (nvidia drivers 440.82)
