Resizing LibreOffice style window causes Gnome-Shell to freeze for 10 seconds

[Mathieu Tarral]

When I open LibreOffce Writer and decides to resize the Style window on the right of the screen (press F11 to toggle this window), Gnome-Shell completely freezes for a few seconds.

I already rebooted and it's 100% reproducible.

I initially reported this bug on Gnome-Shell Gitlab:
https://gitlab.gnome.org/GNOME/gnome-shell/issues/2225#note_715411

You can find more info there (journalctl logs)

I can't seem to reproduce this bug in 20.04. Although LibreOffice is a little slow and unresponsive the rest of the shell continues to animate smoothly the whole time (I left another window animating on top).

So I wonder if this bug is either fixed already or caused by some modification to your machine. Please run this command to send us more information about the system:

  apport-collect 1864301

And if you can please also try booting Ubuntu 20.04 from USB and tell us if you can reproduce it there:

Hi Daniel,

I updated the bug information via apport-collect.

I don't have the time to test Ubuntu 20.04 ISO, sorry.

Thanks.

[Daniel van Vugt (vanvugt)]

Thanks.

When you have time please either test a 20.04 ISO or uninstall all of these extensions:

'<email address hidden>',
'<email address hidden>'

Since so many bugs are caused by extensions we need them to be removed from the equation as a first step. Just disabling extensions is not enough.

Hi Daniel,

I had the time to test the latest 20.04 ISO (today), and I cannot repro the bug so far.

Regarding the gnome-shell extensions, I cleared my ~/.local/share/gnome-shell/extensions and rebooted.

However, i can still trigger the bug.

How can I check the list of installed extensions ?
If I go to https://extensions.gnome.org/local/ I can see 3 system installed extensions:

- Desktop Icons
- Ubuntu AppIndicators
- Ubuntu Dock

Thanks

[Daniel van Vugt (vanvugt)]

Thanks. If the bug isn't in 20.04 then we can declare it fixed already. And if we knew what change fixed it then we could propose a fix to 19.10...
