What's the output of

    gsettings get org.gnome.desktop.interface enable-animations

(and the corresponding entry in `~/.config/gtk-3.0/settings.ini`) on your system? If you're using the default Ubuntu/GNOME session and that's `false`, I'd expect animations to be disabled.

If that doesn't work for you: What's the exact version info from "Help" -> "About LibreOffice" and what's your desktop environment?

( https://ask.libreoffice.org/t/disable-the-blinking-effect-for-the-frame-of-the-selected-element/124127 mentions `org.gnome.desktop.interface cursor-blink`, which is something else.)

Hi Michael,

after switching from x11 to wayland and the border is not blinking anymore.

Anyway, the output of gsettings get org.gnome.desktop.interface enable-animations is false.

The version is 

Version: 25.2.4.3 (X86_64) / LibreOffice Community

Thanks for the additional details.

Does this mean it works as expected in a GNOME Wayland session, but not a GNOME X11 one?

If so: Just to be sure, what's the value of `gtk-enable-animations` in ~/.config/gtk-3.0/settings.ini ?

No problem. Yes, that's what I mean. Sorry, I don´t have that file settings you mention neither in gtk-3.0 folder nor in gtk-4.0 folder.

Odd. It works just fine for me in a GNOME X11 session on Debian testing (gnome-session  48.0-1), so I'm wondering whether this is maybe a bug outside of LibreOffice's control, e.g. some problem with some GNOME components provided by your distro.

2 things you could double-check to narrow this further down:

1) In the "Accessibility" settings in GNOME settings, is the "Animation Effects" toggle off?

2) Does it work if you use a GNOME Wayland session, but run LibreOffice on XWayland, by starting libreoffice using `GDK_BACKEND=x11 libreoffice` from the command line?

Hi again,

1) Animations (Accesibility > Seeing > Reduce animation) is OFF.

2) I if run that command (GDK_BACKEND=x11 libreoffice) while being on a session on Wayland, the mentioned frame blinks while being selected.

This is the version I'm using:

I downloaded it from the Libreoffice official site. I'm on Ubuntu 24.04. Let me know if you need more details.

Thanks for the additional info. I can actually reproduce in an Ubuntu 24.04 VM with GDK_BACKEND=x11, but not when LO runs as a native Wayland app.

I cannot reproduce in my development setup on Debian testing, though.

I don't really have any further ideas at the moment, am still wondering whether this might be some issue in the GNOME/GTK stack in Ubuntu 24.04, rather than in LibreOffice.

The below is the LibreOffice logic to enable/disable animations, which looks OK to me:


bool GtkSalFrame::GetUseReducedAnimation() const
{
    if (!m_pWindow)
        return false;
    GtkSettings* pSettings = gtk_widget_get_settings(m_pWindow);
    gboolean bAnimations;
    g_object_get(pSettings, "gtk-enable-animations", &bAnimations, nullptr);
    return !bAnimations;
}
