Description

Hello,

Since I don't have the deb version for version 14.0.0, I installed the Flatpak version for Ubuntu 25.10 Gnome.

However, while the application installs correctly and opens normally, it is unusable. The real-time clipboard syncing does not work. I should note that the icon is present in the GNOME notification area. However, when I try to paste an item from the clipboard into a window, it doesn't work either.

  1. When I copy text to the clipboard, the copied item is not added to CopyQ.
  2. Even when adding text manually to CopyQ, when I select it to copy to the clipboard and then try to paste it into another window, nothing happens, and no element is pasted.

I can't tell you if it worked properly with version 13.0.0 in Flatpak, as I only chose Flatpak now. In the deb version 13.0.0, it works correctly.

Thank you in advance for your help in resolving this issue.

Research direction
Investigate whether the Flatpak sandbox is preventing D Bus access for clipboard operations. Check if CopyQ's use of Qt's clipboard interfaces is affected by sandboxing. Look at the Flatpak manifest for any missing permissions or required D Bus policies. Also verify if the issue is specific to GNOME Shell's clipboard implementation.
