Description john.kirk 2018-08-02 23:38:10 UTC
Description:
Hello,

After saving a document with many comments (i believe the problem is here), and changing the list to other and back scrolling becomes slow and right button menu opening as well. 

I found out that to happen in 5.2.7 5.4.5 6.0.6 and 6.1 RC2 and connected to libreoffice-gtk3 component (details here https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=890638). In Kubuntu 18.4.1  with Calc 6.0.3 the bug doesn't happen.
 

After File->Reload everything is OK. 

Best wishes,
John

P.S. The document cannot be sent. 


Steps to Reproduce:
Save a document and change the list to other and back. 

Actual Results:
Slow scrolling.

Expected Results:
Not slowing.


Reproducible: Always


User Profile Reset: No

It is important to use newer version of Ubuntu - 18.04. 

From your info i could suggest that it is 16.04.1. 

The bug is also absent on Debian 8 with GTK2,3 VCL (https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=890638), but happens on Debian 9 and Ubuntu 18.04 with GTK2,3 VCL. 

Probably some library difference makes the bug happen.

Comment 5 john.kirk 2018-08-31 09:24:59 UTC
Since the bug reproduces on Fedora 28 and Linux Mint 19 as well, it is probable that all GTK2,3 distributions after 2015-2016 reproduce the bug.

You can't confirm your own bugs. Moving it back to UNCONFIRMED until someone
else confirms it.

The saving is awfully slow (and has apparently always been that way, since 3.6.7 at least), but after it completes, I do not notice any slowdown in the scrolling.

It is important to use GTK2, GTK3 VCL and change the sheet after saving to reproduce the bug.

I made sure to change sheet back and forth now, but no slowness.

Dear Reporter,
Could you please try to reproduce it with a master build from http://dev-builds.libreoffice.org/daily/master/ ?
You can install it alongside the standard version.
I have set the bug's status to 'NEEDINFO'. Please change it back to 'UNCONFIRMED' if the bug is still present in the master build
Comment 14 john.kirk 2018-12-02 22:15:24 UTC
Dear Developer,

The bug reproduces in 6.3.0.0.alpha0+.  

Best wishes,
