> After commit b944841173... I can't start GUI Emacs.
> 
> I did:
> ./configure && make

> And when I start Emacs with "emacs -Q" I get:
> X protocol error: RenderBadPicture (invalid Picture parameter) on protocol request 138
> When compiled with GTK, Emacs cannot recover from X disconnects.
> This is a GTK bug: https://gitlab.gnome.org/GNOME/gtk/issues/221
> For details, see etc/PROBLEMS.

We need you to start Emacs under GDB, passing Emacs the command-line
option '-xrm "emacs.synchronous: true"', and then show the backtrace
inside GDB.  That should produce a much more useful backtrace than the
one you posted.

Why are you unable to run GDB?
