I can reproduce the bug now using jedit (instructions from duplicate bug 1951879).

So far 'jedit' is the only affected app I can find. And I can unfreeze the shell by logging in remotely and killing the 'java' process.

Annoyingly, building gnome-shell manually (even from Ubuntu source) doesn't exhibit the bug. I'm missing something.

Found it. The problem is caused by having both:

  Ubuntu Dock
  Ubuntu AppIndicators

enabled AND an app like jEdit that uses AppIndicators.

Fix proposed: https://github.com/micheleg/dash-to-dock/pull/1599

These are two different bugs actually, as the right-click one on startup isn't due to missing texture but to private window to have a size yet.

However, the handling can be similar.

This was fixed in gnome-shell-extension-ubuntu-dock_72~ubuntu1
