[Bug 1396244] Re: Unlocking the phone over dialer is very slow

 

An easy but not necessarily pretty fix is to revert the commit that
added greeter-fullscreen switching to the dialer [1].  It will leave us
with a black bar where the panel is, but that's probably better than a
jittering experience.

Of course a real fix would be better.  Either make this change quicker
(do we think it's actually a complicated operation or just poorly
performant?), or only have it make the change when needed (i.e. we
actually expose the greeter) instead of every time the greeter shows.
Or both.

For the latter, we'd probably need some way to signal what's happening.
Maybe an exposed DBus property much like "Active" but named something
like "Shown" to indicate if the greeter itself is visible.
