Description opendreas 2022-02-03 18:48:23 UTC
Description:
When I try to resize the properties window on the right side, the system stops responding to the mouse, only the keyboard works, several cores are loaded at 100%. After logout and login, the LibreOffice process continues to run and load the CPU.
This is a scaling issue. I have a 4K display and 225% scale.
You can reproduce this by setting the scale to 200% or more. Below 200% the issue does not occur.
And this issue is only on tab with properties, there is no problem on other tabs.

Steps to Reproduce:
1. Scale 200% or more
2. Try to resize the properties window on the right side 


Actual Results:
the system stops responding to the mouse
several cores are loaded at 100%

Expected Results:
The system will not freeze.


Reproducible: Always


User Profile Reset: No

on a 4k screen with 200% scaling (and I even tried 300% scaling).

I am wondering whether this somehow related to your use of KDE versus
GNOME on my end? I.e., whether the issue might be the KDE integration?

Any chance you can give it a try with the gtk3 VCL?

Victor, can you please share the version and desktop environment you are
using? You can copy that from the "About" menu item in LibreOffice.

You can reproduce this for example on openSUSE Tumbleweed Live with KDE Plasma.

I tried openSUSE Tumbleweed Live with Gnome 42 and LibreOffice 7.3.3.3, the system doesn't freeze, but I can't scale the first properties tab correctly, it takes up 2/3 of the screen.
But I have no problem with LibreOffice Flatpak.

If I'm not mistaken, he uses Arch Linux with KDE Plasma.

I guess it is about Sidebar-Properties. Would be good and needed to be precise when submitting. Also to write for Sidebar both docked and not.
Anyway, no repro in Mint with gtk3 and kf5.
Comment 5 Michael Weghorn 2024-08-22 15:56:38 UTC
Can't reproduce on Debian testing with a current LO development version (git master as of 2c9821d391c243ae83a408163f054d7a7a9a1daa) and the kf5 VCL plugin, in a self-compiled current Plasma master Wayland session.

Do you still see this issue with LibreOffice 24.8?
Comment 6 Michael Weghorn 2024-08-22 15:59:38 UTC
In case it's still reproducible with a current version: Please give more details on your monitor setup (one or multiple screens, what resolution?)
