I have one more data point. Apparently I do not need to "click" on the emacs frame to make the line numbers reappear. They reappeared seemingly randomly or just as I was just hovering the mouse over the emacs frame.. odd. This happened just as I was preparing to record "line num reappearance on click" effect, but the line numbers reappeared by themselves even before I clicked. -- Kaushal Modi --94eb2c0c8d1273b89905540ba82c Content-Type: text/html; charset="UTF-8" Content-Transfer-Encoding: quoted-printable

Alternatively, instrument your functions that reset
display-line-numbers to log messages to some buffer with useful
information, such as the Lisp backtrace, and when the problem happens,
examine the log for clues.

I will set u= p the Lisp watchpoints and debug more, thanks.
