Clipboard stops synchronizing between GUI applications on Fedora GNOME Wayland

I’m experiencing a clipboard synchronization issue on Fedora GNOME running on Wayland.

Applications initially share the clipboard normally. However, once an application copies something, it stops receiving clipboard updates from other GUI applications and continues pasting its own previously copied content.

Logging out and back in resets the behavior.

System information

  • Fedora Linux 44 (Workstation Edition)
  • GNOME 50
  • Wayland
  • Linux 6.19.14-300.fc44.x86_64
  • 64-bit

Applications tested

  • Firefox (RPM)
  • Vivaldi (Flatpak)
  • Zed (standalone installer)
  • GNOME Terminal
  • GNOME Text Editor

Reproduction

  1. Copy text in Firefox.
  2. Paste into Vivaldi → works.
  3. Copy text in Vivaldi.
  4. Copy different text in Firefox.
  5. Paste into Vivaldi.

Expected: The newly copied text from Firefox is pasted.

Actual: Vivaldi pastes the text it copied earlier.

The same behavior occurs with all the applications listed above. Copying and pasting within the same application continues to work normally.

Additional observations

  • wl-copy and wl-paste work correctly.
  • wl-paste always reports the latest clipboard contents, including content copied from GUI applications.
  • The issue occurs across RPM, Flatpak, and standalone applications.
  • The issue is not limited to a particular application or toolkit.

Troubleshooting performed

  • Logged out and back in (temporarily resets the issue).

  • Disabled all GNOME Shell extensions.

  • Restarted IBus.

  • Verified xdg-desktop-portal and xdg-desktop-portal-gnome are active.

  • Verified the Wayland clipboard using:

    echo "hello" | wl-copy
wl-paste

  • Ran:

    gsettings set org.gnome.desktop.interface gtk-enable-primary-paste true

    (no change).

  • Checked common environment variables (GTK_MODULES, GTK_IM_MODULE, QT_IM_MODULE, etc.) and found nothing unusual.

Has anyone experienced this before or know what could be causing it?

Same issue. Do you use Tiling Shell?

Found this in the journal.

Now going to do disable all gnome extensions and enable them one by one.

These are all the extensions I use

  1. Caffeine
  2. Copyous
  3. Tiling Shell
  4. Appindicator
  5. Places
  6. System Monitor

I was also using Zed editor (from terra) when this issue happened.

I only use three extensions: Blur My Shell, Color Picker, and Dash to Panel. Based on my investigation, I have found no evidence that GNOME extensions are involved in this issue.

There’s another user on here who reported that the clipboard was not operating as expected. Traced it to Zed doing something weird - normal behaviour when zed was not running but copy & paste not reflecting what the user thought was in the clipboard when Zed was running.

Something akin to that scenario, posted in the last week or so.
