Bug Description
I am running ubuntu 18.04 and the okular version is 1.4.3
When I try to use touchpad to scroll, okular can work well at most of time but sometimes it randomly jumps several lines (in most cases, it jumps half page). If I am scrolling upwards, it jumps upwards. Or it jumps downwards if I initially scrolling downwards.
I find that the old verion okular in ubuntu 16.04 is free of this bug.
I also find it has been reported and in the first link below, you can see the bug demo video.

This bug seems due to a qt bug and will take time to be solved completely. Does anyone know how to avoid its influence currently since it is really annoy. I tried to downgrade my current okular to old verion but it seems that I can not do that in ubuntu 18.04 and I have to go with the 1.4.3 version.
If anyone knows how to solve it, please tell me. Really appreciated!
