buzz-desktop crashes on launch under Hyprland (Wayland) with “Error 71 (Protocol error)”

**Describe the bug**
Buzz Desktop starts but immediately exits with a Wayland protocol error. No window appears.

**Steps to reproduce**
1. Install buzz-bin from the AUR on an Arch-based system (e.g. Omarchy) running Hyprland.
2. Launch the app from the terminal or application menu: buzz-desktop
3. See the error and the process exits (no window opens).

**Expected behavior**
The app should open and stay open under Hyprland / pure Wayland without requiring extra environment variables.

**Version and platform**
- Buzz version: 0.4.26-1 (installed via buzz-bin AUR package)
- OS: Omarchy (Arch Linux) + Hyprland (Wayland)

```

**Workaround**
1. Copy the desktop file to your user directory:Bash
`cp /usr/share/applications/Buzz.desktop ~/.local/share/applications/`

2. Edit it:
`nano ~/.local/share/applications/Buzz.desktop`

3. Change the Exec= line to:
`Exec=env GDK_BACKEND=x11 WEBKIT_DISABLE_DMABUF_RENDERER=1 buzz-desktop`

4. Launch Buzz app

This is a known class of WebKitGTK / Tauri issues on some Wayland compositors (especially Hyprland). Forcing the X11 backend works reliably.
