[okular] [Bug 426502] New: Okular occasionally crashes when opening PDF files

Tried 3 times, Okular crashed 2 out of 3 times, succeeded once. Opened Okular manually and opened the file with File/Open, tried 3 times, got 2 successful opens and 1 crash.

[okular] [Bug 421780] Most ways of navigating a document not working (Qt 5.15)
https://bugs.kde.org/show_bug.cgi?id=421780 --- Comment #7 from Bernhard Rosenkränzer --- Created attachment 130671 --> https://bugs.kde.org/attachment.cgi?id=130671&action=edit Partial revert that fixes it The attached patch, a partial revert of the problematic commit, "fixes" the issue (but of course destroys the advantages of using QScroller). I'll keep this in our package until the real problem is sorted out, it's not perfect but better than nothing, at least it restores what was working in 19.12.x -- You are receiving this mail because: You are the assignee for the bug.

https://bugs.kde.org/show_bug.cgi?id=421780 --- Comment #6 from Bernhard Rosenkränzer --- The problem seems to be d->scroller->scrollTo(d->scroller->finalPosition() + QPoint(0, 100 * nSteps), 0); in slotScrollDown() in ui/pageview.cpp not having any effect (even though nSteps == 1) when it is called by the keyboard event and wheel event handlers. I've never used QScroller, so I'm not familiar with its internals -- but at a first glance, looks like a Qt bug and makes me wonder why others aren't seeing this (we're using stock qt 5.15). -- You are receiving this mail because: You are the assignee for the bug.

[okular] [Bug 421780] New: Most ways of navigating a document not working (Qt 5.15)
https://bugs.kde.org/show_bug.cgi?id=421780 Bug ID: 421780 Summary: Most ways of navigating a document not working (Qt 5.15) Product: okular Version: 1.10.1 Platform: OpenMandriva RPMs OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: general Assignee: okular-devel@kde.org Reporter: b...@lindev.ch Target Milestone: --- SUMMARY Navigating a PDF document (probably any other content too) doesn't work properly in okular 1.10.1 with Qt 5.15-rc2, Frameworks 5.70, Plasma 5.18.90. The right-hand scrollbar works. As does grabbing the PDF with the mouse and moving it up and down. But all other ways to move around in the PDF seem to be ignored: mousewheel on the pdf, arrow keys, trying to move the focus in the thumbnails panel, PageUp/PageDown keys, ... There are no error messages in the konsole session from which okular was started. Chances are for some reason okular isn't getting the relevant events when Qt 5.15-rc2 is used. STEPS TO REPRODUCE 1. Update to Qt 5.15-rc2 2. Run okular 3. Try to navigate the document OBSERVED RESULT Mousewheel on the pdf, arrow keys, trying to move the focus in the thumbnails panel, PageUp/PageDown keys, ... do nothing EXPECTED RESULT Mousewheel on the pdf, arrow keys, trying to move the focus in the thumbnails panel, PageUp/PageDown keys, ... work as they always did SOFTWARE/OS VERSIONS Linux/KDE Plasma: kernel 5.7-rc5, glibc 2.31, clang 10.0.1 KDE Plasma Version: 5.18.90 KDE Frameworks Version: 5.70 (with components that have had a 5.70.1 release updated to 5.70.1) Qt Version: 5.15-rc2 ADDITIONAL INFORMATION Chances are for some reason okular isn't getting the relevant events when Qt 5.15-rc2 is used - other applications are not showing similar issues, so chances are it is a changed behavior that needs to be worked around in okular rather than a Qt 5.15 bug. -- You are receiving this mail because: You are the assignee for the bug.
