Page Up/Down scroll only by approximately one scrollbar thickness when “Show scrollbars” is unchecked in the configuration, and scrollbars were not shown before in the current Okular session. Apparently no one noticed before that the video demonstrations have scrollbars hidden. The patch attached to this bug theoretically works fine, but disables smooth scrolling for Page Up/Down completely, so we need a different solution. Probably inside slotScrollUp/Down(). -- You are receiving this mail because: You are watching all bug changes.

I am finishing it now] 4) I go back into the settings and ask for the scrollbars to be hidden 5) The space key is still working properly. 6) I quit okular and start again 7) The bug is is back: the space key scrolls by one line of text. Extra information: I have a HiDPI display, and I might have some non-standard configuration options. For instance, my plasma desktop is scaled by a factor 2 and the server X is started with -dpi 192. I don't know whether this is relevant or not. So the bug is still present in okular 20.12, but depends on some configuration options. In my case, to observe it, okular must be started without any scrollbar. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=421822 Éric Brunet changed: What|Removed |Added CC||eric.bru...@lps.ens.fr --- Comment #24 from Éric Brunet --- I think there's been a mix up between two different issues a) the fact that Scroll Up/Scroll Down or Space moved the document by about one line of text instead of nearly the full displayed height b) the issues about smooth scrolling The original description of the bug was about problem a), but in the comments it drifted to problem b), and eventually the bug was marked as resolved and duplicate of bug 422050. But this is for problem b)! Problem a) is not fixed, and I am reopening this bug. My okular was working correctly in Fedora 32 (Version 19.something of okular, I didn't make note of exact version). I upgraded to Fedora 33 (Version 20.08) and ran into the problem described here. I then upgraded the okular package from fedora rawhide (or 34) in the hope the problem was already fixed: okular-20.12.2-2.fc34.x86_64 But it is not. The bug seem related to scrollbars. I have set up okular so that scrollbars are not set. Then: 1) I run okular on some pdf file. No scrollbar, of course, and the bug is present: pressing the space key moves me down by about one line of text. 2) I go into the settings and I ask for the scrollbars to be displayed 3) The bug no longer shows! Pressing Space scrolls me down by nearly one height of the displayed text. 4) I go back into the settings -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=421822 --- Comment #17 from Kamil Dudka --- (In reply to Nate Graham from comment #15) > Are we all talking about the same thing? Nope. For me the issue is the smooth scroll animation that blocks the scrolling. It makes it impossible to scroll large documents quickly with keyboard. I believe that the scroll distance can be to some extent configured as mentioned in another bug: Settings -> Configure Okular -> General -> Page Up/Down overlap -- You are receiving this mail because: You are watching all bug changes.

For me the issue is mostly the smooth scroll animation that occurs on pgup/pgdn rather than the specific scroll distance - but both are annoying when I'm used to being able to page down 30 pages in a second or two by just holding pgdn, and both seem to be caused by the same commit indicated in comment 6 -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=421822 --- Comment #12 from triffid.hun...@gmail.com --- I've found that my patch works if you stick with pgup/pgdn, but the scroll position gets confused and jumps suddenly if you subsequently use scroll wheel - apparently I need to update another control somewhere for it to work properly. What exactly I'm missing I'm not sure - my bread and butter is firmware, not Qt/GUI programming ;) I'm keeping the patch in my local set, this new glitch is vastly less irritating than the issue this bug is about, but I hope one of y'all can make a better patch and post it here! -- You are receiving this mail because: You are watching all bug changes.

It's parent commit 13bb95c253332145db0609ffd8fbdad3bed49fff is fine. I tried to revert the commit from a top of the master branch to see if it is the only commit that is related to the problem, but there were further changes in the same code in later commits and therefore the revert caused merge conflicts. I am not familiar with the code to resolve those conflicts properly, so I didn't proceed with this. -- You are receiving this mail because: You are watching all bug changes.

Thanks for the hint - eventually I found out that what I needed was QT_PLUGIN_PATH, which should be set to /lib/plugins, and then indeed okular succeeds to run. The KDE_INSTALL_PLUGINDIR is used only as an installation path, and since I am not running as a root I cannot install compilation results into a system-wide dir, especially since I want to run multiple versions. In any case, now I have the two points for bisection (v19.12.3 & v20.04.1), where the problem occurs in one but not in another.

https://bugs.kde.org/show_bug.cgi?id=421822 --- Comment #3 from quant...@gmail.com --- It is a bit strange that the problem doesn't reproduce in your environment. Initially I asked about the problem in arch's forum (here: https://bbs.archlinux.org/viewtopic.php?id=255604), and waited for somebody to confirm the problem before submitting the bug report - to make sure that the problem is not specific to my machine. I see that arch's package just builds okular as is, without adding any distribution-specific patches (here is the relevant link: https://git.archlinux.org/svntogit/packages.git/tree/trunk/PKGBUILD?h=packages/okular), therefore I would expect the problem to be easily reproducible. In addition, the problem does not seem to be caused by okular's dependencies, since when I downgrade okular to a previous version (without changing anything else on the machine), the problem disappears. I tried to bisect the problem in order to find the exact commit which introduced the problem, but unfortunately I am unable to execute the manually built okular: when I try to run it, I get an error message saying: "Unable to find Okular component: The shared library was not found", which is somewhat strange, since I build the program with the following arguments: cmake -DCMAKE_INSTALL_PREFIX= -DCMAKE_BUILD_TYPE=Debug

I just realized that versions 19.12.3 and 20.04 (and not 20.0.4, as I written originally) are package versions in Archlinux, and not okular versions. -- You are receiving this mail because: You are watching all bug changes.
