Both gnome-shell animations paint their own independent static copy of
the desktop background on top of the live wallpaper actor: the
workspace-switch swipe (WorkspaceBackground) and the lock screen
(UnlockDialog, which already applies native blur). Patch both
private _createBackground methods to hide the static clone /
attach a shared-content actor so the live video shows through
instead, gated on the existing apply-to-lock-screen settings
An early seek right after set_state(PLAYING) raced the pipeline's
preroll and GStreamer silently dropped it, so a configured custom
rate only took effect after the first EOS loop-restart. Instead,
flag the pending seek and fire it from the first ASYNC_DONE bus
message, once the pipeline is actually ready to seek.

Throttle the EOS loop-restart seek so a fast-looping clip can't fire
back-to-back blocking flush seeks on gnome-shell's main loop, which
was severe enough to freeze the whole desktop. Also apply the
configured playback rate immediately on start instead of only from
the first loop restart.

Gst.init() has no async variant. If the plugin registry cache is stale
(e.g. right after a system update), it synchronously rescans every
plugin, spawning gst-plugin-scanner per plugin and probing hardware
for codecs. Since gnome-shell is single-threaded and is the
compositor, that can freeze the whole screen for several seconds,
same as the blocking UPower proxy lookup fixed earlier.
Set GST_REGISTRY_UPDATE=no when a cache already exists so Gst.init()
trusts it and returns immediately, then refresh the cache in a
throwaway subprocess afterward so it doesn't go stale forever.
