workspaces don't show when bar is started until I focus on an app

[gavsiu]

Workspaces show and work when clicked, but it doesn't show up right after I start my panel. The area is blank until I change my focus. When after logging in, it doesn't show until I open an app.

Until the first read call completes and a whole line is read you're not piping anything at all into the bar.

But everything else displays?

Oh I see, anyway the problem lies in the script and not in bar, double-check the script and re-open this in the unlikely case there's a rendering problem in bar.
