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 Additional Info:

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. Best wishes, John

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.
Ok. Best wishes, John
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.

(In reply to Buovjaga from comment #8) It is important to use GTK2, GTK3 VCL and change the sheet after saving to reproduce the bug. Best wishes, John
This bug is also related to the bug 119650 (the same attachment). Best wishes, John

Dear Developer, Scrolling is almost identical to 'before saving' but CPU usage is ~2x and changing sheets still happens with a 2-3 sec lag. Debian 9, Debian 10 while Debian 8 is not affected. Appimage Version: 6.3.4.2 Build ID: 60da17e045e08f1793c57c00ba83cdfce946d0aa Best wishes, John
Not reproducible for me with LibreOffice 6.4.3.0+ built at home under Ubuntu 18.04 x86-64 with Gnome DE. Only changing from a sheet to another is long, no slowness problem with scrolling or right-click menu.

I couldn't reproduce the problem. I think it might just be a problem based on the kind of computer the user is using. Is it a temporary slowing or does it slow down until the application is restarted? If it is a temporary thing then it might just be that your computer is using a lot of your CPU and that slows down and the scrolling gets laggy but if not then it might be a bug.

This slowness I do repro. It doesn't depend on gtk. I repro it in 6.3, 5.0 and oldest of Linux 43all repo. Also on Windows. After you switch once between all the sheets, the slowness is gone.

When run "SAL_USE_VCLPLUGIN=gen libreoffice", the slowness is gone after switching sheets. Best wishes, John
