after add 'x11' feature, everything works fine

bevy = { version = "0.14.0-rc.2", default-features = false, features = [
    "bevy_asset",
    "bevy_audio",
    "bevy_state",
    "serialize",
    "vorbis",
    "bevy_winit",
    "bevy_render",
    "bevy_sprite",
    "bevy_ui",
    "bevy_text",
    "bevy_core_pipeline",
"x11",
    # Can be removed later, temporary fixes for a bug in "0.14.0-rc.2"
    "bevy_scene",
    "bevy_pbr",
    "ktx2",
    "zstd",

] }
