Created attachment 130402 [details] demonstration video When viewing a >1 page document which does not fit vertically on the screen, but does fit horizontally on the screen, in view mode "facing pages", okular can not scroll properly to the end of the document: when the mousewheel scrolls down, it jumps back to the top of the second-to-last page (repeating this jerky movement as long as the wheel is scrolling).

Can't reproduce, does it also happen if zoom is say 60% instead of 100% ? Do you have view -> trim view -> trim margins selected? Is it specific to that PDF or you can reproduce it with any?
Thanks -- yes, it happens at any arbitrary zoom and with any PDF. "Trim margins" was not selected, but it makes no difference. Did you ensure that the document was clipping at the top/bottom but not left/right? I could post okularrc and okularpartrc if handy (but which -- .config/. or .kde/share/. ?)
.kde/share is junk from kde4 era Yes, i made sure of that. I guess you can try posting those to see if it helps, cleanup the recently open files if you don't want to leak that info.

Here are the configs. Let me know if there's anything else I can do or provide.
Ah, you're using non continuous scrolling. Yes i can reproduce now.
