--- Comment #13 from roger truong <dragonrmar...@gmail.com> --- After looking through the rest of pageview.cpp, I think I narrowed down the problem to the auto limit_value function. https://invent.kde.org/kde/okular/-/blob/master/ui/pageview.cpp#L5369 https://invent.kde.org/kde/okular/-/blob/master/ui/pageview.cpp#L5400 (In reply to Keziolio from comment #10) > Regarding the original bug, the behaviour of the scroll events is programmed > to be literally the same as it was before, probably QScroller::scrollTo > behaves in a suboptimal way if it's flooded with events, I'll see if > something comes to mind Changing the value for nSteps to 2000 from 200 brought back the scrolling from previous versions. It seems that the regression may be in animation speed rather than scrolling if none of the code has changed. It also brought up another bug in the animations with the Contents view. When continuously scrolling, the headings don't advance as they did in 1.9.x. It jumps to whatever heading the current page is on once scrolling has stopped. I'm unsure if this qualifies for a separate bug report, as the synchronous nature of the animations lead me to believe these bugs may be related. The effect can be seen in Contents pane of the videos attached in the OP as well. -- You are receiving this mail because: You are the assignee for the bug.
