Ubuntu Dock briefly glitches (has a border and rounded corners) when unlocking the screen or VT switching

[Daniel van Vugt]

Ubuntu Dock briefly has a border and rounded corners when it restarts (after VT switches or unlocking the screen). It looks like it takes a couple of frames to apply the correct appearance.

Possible solutions in order of preference:

* Apply the extension's stylesheet before rendering the dock. That might just fix it.

* Apply the same slide-in animation (after LP: #2058468) to unlocking the screen.

It seems the stylesheet *is* applied before the extension is activated. But even if I add an extra wait for "custom-stylesheets-changed", that's still too early for the dock/dash to know about the new style that's already been loaded and signalled. There's some other delay causing the dock to be rendered in the old style for the first frame or so.

Oh "custom-stylesheets-changed" happens several times on startup so maybe I hadn't waited for it to be signalled enough times. I'll try to revisit this again in the coming weeks.
