That is almost certainly a sign you are blocking the main loop with a
call somewhere in your Thread.

But that doesn't really seem to be the case. Weird.

At first DrawingArea's Widget.ExposeEvent gets called fine, even after
you start the thread. It's only after a while that suddenly it goes
blank. That's very strange.

I was about to blame this as a GC issue, but it doesn't happen if you
don't start the thread. At least, I've not seen it (perhaps the thread
is causing GC pressure. I doubt it, though).

The diagnostics I've tried so far are going to extra effort to make sure
the Windows stay in scope, and slowing down your thread to sleep(1000).

Anyway, at first glance you're not misusing GTK. The app's UI isn't
freezing.
