Well, that looks like bad news: you presumably wanted every widget to be
more than 1x1 pixels.

Sorry, I don't have any insights into why this would be happening or
whether it's vim or Gtk that regressed.

If in doubt, more information is better than less information. Hopefully
it's always the GUI thread that's interesting (as it looks as though it
was on the one you quoted), so "bt" rather than "thread apply all bt"
would be sufficient.
