    [x11] Disable synchronized resizing for Xwayland < 1.21 · 76af96bc
    Vlad Zahorodnii authored
    In case Xwayland does not use multiple buffers, the currently attached
    buffer is going to be destroyed if the frame window is resized. It may
    render the previous and the current window pixmap invalid and thus result
    in visual artifacts when an X11 client is being interactively resized.
    
    In order to avoid the visual artifacts, this change disables support for
    synchronized resizing for X11 clients if the version of Xwayland is less
    than the version in which Xwayland started using multiple buffers, i.e.
    1.21.
