Hello

Every week, after updating local repositories (git pull), I build Emacs
27.0.60 and
Emacs 28.0.50.
Since the 14 of February 2020, everything is OK with Emacs 27.0.60 but
Emacs 28 starts in a window with a blank frame without displaying any
character. Keyboard is active and I quit with Ctrl-x Ctrl-c.

Yet, everything is Ok when running same Emacs 28 in a terminal with command
.../Emacs.app/Contents/MacOS/Emacs -nw

On the other hand, everything is OK with Emacs 27.0.50

Thinking that it was a macOS problem, I look at the log for the files
src/ns* and I downgrade the repository with the command
git checkout f674c905dc98a4617c40c4bc115462b4ad2ebfc2
and rebuild Emacs 28. So eveything is OK

I can't explain why updates after this commit cause this behavior.

Hi Philippe,

I pushed a possible fix for this to the master repository last night.
Could you please try it again?

Hi,

I rebuild Emacs this morning with last commits, but now, no window is displayed and Emacs crashes. I join the trace at this mail.
