I am using the following emacs build, from
http://emacsformacosx.com/ on an updated Mavericks installation: "GNU
Emacs 24.3.50.1 (x86_64-apple-darwin, NS apple-appkit-1038.36) of
2014-01-27 on bob.porkrind.org"
I'm disabling the native fullscreen functionality in my conf file
(setq ns-use-native-fullscreen nil) and I have the OSX option
"Displays have separate spaces" disabled.
While avoiding the native fullscreen does two very welcome things
(the fullscreen window remains on the current space and the other
monitor, if attached, is not greyed out) there are two problems:
1) Going fullscreen works only on the primary laptop monitor (I'm
using a macbook pro) but not on the secondary monitor on the display
port. When the emacs frame is on the secondary monitor, "M-x
toggle-frame-fullscreen" has the following results: - An animation of
a small black rectangle goes out of the screen (headed to the lower
right part of the screen - please note the secondary monitor is on
the upper left wrt the primary one, don't know if this is related or
not). - A brief macosx error sound is played. - The screen is now
empty and emacs is nowhere to be seen, neither primary nor secondary
monitor. - The only way to get the emacs frame back is blindly
calling toggle-frame-fullscreen again - the frame then returns to its
previous position.
2) Even on the working primary monitor there is still a very slow
scaling transition to fullscreen (and back). I find slow animations
in Maverick to be annoying and nausea-inducing. Users that are
disabling native fullscreen functionality are probably trying to
disable the slow transition too (most other open source apps that
give the user the option to disable the native fullscreen
functionality, such as VLC and iterm2, do exactly this and avoid the
slow animation entirely). It seems reasonable to either disable the
animation when native fullscreen is disabled or add and additional
option to disable it and/or control how fast it is (if I've missed
one I'm sorry, please point it out to me).
I've tested one of the several unofficial osx emacs versions that
were fullscreen-patched in the past
(https://github.com/xajler/emacs24-macosx-lion-fullscreen) and it
works as intended on both counts: it goes fullscreen on both monitors
and without any animation whatsoever.
If there's anything I can do to help, test etc, please do tell me. I
am confortable with building software from source and it is not a
problem for me to checkout and build the latest sources if
necessary.
Many many thanks for all the amazing work that the emacs developers
have done in the past and are still doing on this amazing editor.
Keep up the good work!
