Copying from an Xwayland app disables recording clipboard history until the server is restarted

[MrStickyPiston]

System information

• Version: v0.19.3 (d2f38c2)
• Build info: GCC 15.2.0 - Release
• Provenance: nix
• OS: NixOS 25.11 (Xantusia) - 25.11
• QT Platform: wayland
• DE: Hyprland/Wayland

Describe the bug

Copying from a Xwayland window results in the clipboard being blocked until the server is manually restarted. The other vicinae features still work in the meantime, and its also possible to select clipboard entries in the menu and copy those to the currently selected entry.

To Reproduce

1. Open a wayland application, such as IntelIJ IDEA.
2. Copy something. It does not get copied to the clipboard.
3. Copying something else (non-Xwayland) also does not work anymore.

Expected behavior

In the first place i expect the clipboard not to be blocked when copying fails. Additionally, i would expect to be able to copy from Xwayland in the first place.

What do you mean by "the clipboard is blocked" ?
Interested in additional feedback for this one, I can't reproduce on my end (Hyprland).
Please also provide your Hyprland version as well.

With 'the clipboard is blocked' i mean that whatever thing i do i cant copy to it anymore, but i can select items in the vicinae clipboard menu to move them to the first entry. I can paste.
