Sorry, it is still unclear to me.
I understand that you use your touchpad for scrolling. Therefore, you should
have pixel-wise scrolling. What we call “smooth scrolling” in Okular (since
release 1.10 / 20.04), is not applied to pixel-wise scrolling with a touchpad.
Smooth scrolling means to us that the content moves stepwise (like when you
press the arrow keys), but with an animated transition.
(Apparently you have a 141dpi screen, so I estimate between 150% and 200% your
Okular turns on tiled rendering.) Is the problem that the content briefly
disappears when you scroll at high zoom scales?
(Another theory is that your Okular does not turn on tiled rendering for some
reason, and so operates with too big pixmaps.) Is the problem that the
performance is bad when you scroll at high zoom scales, so the content moves at
irregular large steps instead of pixel-wise?
