3) C-g
"Quit" will flash in the minibuffer, but the cursor will remain trapped
in the minibuffer. C-] will still correctly leave the
minibuffer. Holding down C-g for several seconds will eventually cause
the cursor to correctly leave the minibuffer.
This behavior began within the past week or so, possibly caused by
Ubuntu system updates, as I did not knowingly change any meaningful
Emacs variables or install any Emacs packages.
The issue is similar to those described here:
