The new asynchronous UI flickers quite a bit before data has loaded

[taotriad]

With the new asynchronous UI behaviour also comes quite a bit of flickering; first of all the flickering on update (not that bad, since it's typically only every 5 seconds or so), second of all the flickering before data is found. The latter is really annoying.

The latter should be straightforward to fix. The former will need a bit of revamping of the UI behaviour; a revamping that we should do anyway, but it'll take quite a bit of effort, so that's out of scope for this issue.
