I'm running libreoffice under Gnome desktop.

.. I'd actually believe this is a Gtk3 and/or GNOME bug?

What happens if you downgrade Gtk3 to 3.20.9-1 or so? (http://snapshot.debian.org/package/gtk%2B3.0/3.20.9-1/#libgtk-3-0_3.20.9-1)

This report and #836531 (I think) started happening with the new Gtk, because at least for #836531

[2016-08-20] libreoffice 1:5.2.0-2 MIGRATED to testing (Britney)
[2016-08-14] Accepted 1:5.2.0-2 in unstable (medium) (Rene Engelhard)

^ this happened before

[2016-08-30] Accepted 3.21.5-1 in unstable (low) (Andreas Henriksson)

^this and the report was from 2016-09-03....

Cc'ing #836531 and -gtk-gnome.

Rene

Downgrading Gtk3 to 3.20.9-1 fixes the bug!!

So, it is probably a bug in Gtk3 or in the way that LO uses Gtk (because no other Gtk app seems affected).

Cc'ing #836531 and -gtk-gnome.

Thanks,

Daniel.

Does that also help for the "-gtk3 makes it slow in xfce" bug (#836531)?
Then those indeed are the same one and should be merged.

So, it is probably a bug in Gtk3 or in the way that LO uses Gtk (because no other Gtk app seems affected).

Upstream says:

10:51 <@caolan> might be the same thing as
https://bugzilla.redhat.com/show_bug.cgi?id=1373933 which I'm
looking at right now
10:52 < IZBot> bug 1373933: Fedora-['libreoffice'] unspecified/unspecified NEW
object selection and edit freezes libreoffice for several seconds
10:52 < _rene_> 17:57 < _rene_> caolan: remember on how I asked about Gtk
3.21.x? http://bugs.debian.org/837356...
10:52 <@caolan> I'd say its the same thing, especially cause of "Downgrading
Gtk3 to 3.20.9-1 fix it"
10:52 <@caolan> I'm bisecting gtk itself at the moment
10:53 < _rene_> yeah, sounds like it afte reading the rhbz bug

For -gtk-gnomes sake:

commit 0f116135f4a5033ce4e9dfa19f10624701fa615c
Author: Matthias Clasen <mclasen@redhat.com>
Date: Fri May 6 10:12:14 2016 -0400

Avoid emitting ::style-set by name

GtkStyle is deprecated, but we still emit ::style-set quite
a bit, so lets at least not be slow while doing it.

in Gtk caused it, but it's fixed in LOs master (https://cgit.freedesktop.org/libreoffice/core/commit/?id=ef7abe81df10cb8a8c04afbb1fbe700f94e73f04)

Will backport.
