SUMMARY


STEPS TO REPRODUCE
1. Open a file in LibreOffice
2. at the beginning the mouse wheel scrolls the document up and down 
3. at a certain point it no longer scrolls; so you switch to another window and afterwards if you return to the previous document (left open) the mouse wheel restarts working again (for a while). And so on...

OBSERVED RESULT

temporary failure in scrolling a LibreOffice document

EXPECTED RESULT

a regular and constant mouse functionality, which should always be able to scroll a document

Since this bug began wuith KDE 5.18 it could be (I'm not sure, but they have in common the display) related with this other: https://bugs.kde.org/show_bug.cgi?id=417613

Comment 2 Nate Graham 2020-02-18 22:43:59 UTC

This is a GTK bug. See https://gitlab.gnome.org/GNOME/gtk/issues/558 and https://bugzilla.gnome.org/show_bug.cgi?id=750870

Comment 3 Duns 2020-02-19 07:08:35 UTC

Thank you. I believe you're right, but I don't understand (I'm not a developer) what I should do to avoid this bug. Maybe using gtk 2 instead than gtk 3?

Comment 4 Duns 2020-02-19 08:57:10 UTC

Yes, disabling gtk3 in LO fix this bug, but it is less beautiful.
What about the patch in https://bug750994.bugzilla-attachments.gnome.org/attachment.cgi?id=305934

Comment 5 Nate Graham 2020-02-19 14:36:30 UTC

You can also use the KDE backend for LibreOffice, rather than the GTK3 one.

Comment 6 Duns 2020-02-19 14:41:58 UTC

Yes, I know, but there are lots of problems with KDE-libreoffice...

Comment 7 Duns 2020-02-19 14:43:01 UTC

Do you know if apply that patch is sure?
