Describe the bug decoration set false doesn't work on Wayland KDE. When running the example "decorations" (example/decorations.rs), press "space", the window decoration shluld disappear, then press "space" again, the window decoration should appear. But it only works on X11 or wayland gnome. When using KDE Wayland, the window decoration (including titlebar) always shown, even press "space" again and again. Steps To Reproduce

  1. clone tao repo.
  2. cd tao directory.
  3. GDK_BACKEND=wayland cargo run --example decorations

    set "GDK_BACKEND=wayland" environment variable and run decorations example then press "space" key.

Expected behavior When press "space" key, the window decorations (including the titlebar) disappear. Press the "space" key again the window decorations appear.

I have changed the gtk3 source code according to #https://gitlab.gnome.org/GNOME/gtk/-/issues/5479 and compile the gtk3. This problem seems to be solved in gtk3 application and gtk-rs application. But when I link the customed gtk3 lib to tao(by using LD_LIBRARY_PATH), It doesn't work with tao, tao still has this bug.

I have tested it on Windows subsystem for Linux. It works well on wsl wayland, but doesn't work on wsl x11. Very strange.
