[Message part 3 (text/plain, inline)]

When starting with

    (push '(fullscreen . fullboth) default-frame-alist)

in early-init.el, apparently Emacs get stuck in an infinite loop after calling [EmacsView waitFullScreenTransition]. Please see the attached backtrace. I also tried moving that command around: in init.el, in emacs-startup-hook, all yield the same result. 

Toggling fullscreen after successful startup (by not trying to start in fullscreen) works ok. Also creating new frames with '(fullscreen . fullboth) in default-frame-alist works well.

Looks like this bug was introduced by bbc48b263485c26c6823eabdbbd7e9af62178e34
