Use scroll wheel to scroll through document OBSERVED RESULT Scroll wheel does nothing EXPECTED RESULT Scroll wheel moves forward and backwards through document SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: (available in About System) KDE Plasma Version: 5.24.5 KDE Frameworks Version: 5.95.0 Qt Version: 5.15.3 ADDITIONAL INFORMATION
Are you sure your mouse wheel didn't break?
(In reply to Albert Astals Cid from comment #1) > Are you sure your mouse wheel didn't break? Yes, I can use it in other applications. It just does nothing in Okular.
A bit more information. It will scroll if I've set view mode to continuous so that there is a scroll bar, but if there is no scroll bar it doesn't advance to the next page.
If you have a mouse with free spinning mouse wheel, which doesn’t scroll in discrete steps, this is Bug 443404. You can actually advance to the next page, but you need to sroll so fast that Okular sees so much scrolling at once that it is considered a discrete step. With a touchpad this is easy to do, but still very hard to control. :(

With a touchpad this is easy to do, but still very hard to control. :( Yes, that does look like the issue. It was fine in the previous version.
Then I make it a duplicate. > It was fine in the previous version. May also be related to updating some mouse driver or other library at the same time, which previously didn’t make the bug visible. *** This bug has been marked as a duplicate of bug 443404 ***
