hi,
sorry for my English is not good, if you found any strange words and grammar.
I am using ibus and rime engine as chinese input method in gnome 41.3 of Linux
5.16.3-arch1-1 x86_64, xwayland.
i found ibus can't show any input candidate menu in emacs,
after reinstall system got emacs from   pacman -S emacs,
but work fine in other application such as gnome-shell, firefox.

after searched in www,
i tried these method to solved problem:
 a.
   export LC_CTYPE=zh_CN.UTF-8
   export XMODIFIERS=@im=ibus
   export GTK_IM_MODULE=ibus
   export QT_IM_MODULE=ibus
   cp /usr/lib/gtk-3.0/3.0.0/immodules.cache /usr/lib/gtk-3.0/3.0.0/gtk.immodules.cache
   ibus-daemon -d -x

   # it  can't work.

 b.
   i found a site say to use "lsof" checking if 'im-ibus.so' is called  for emacs,
   then i use follow command:
      emacs -q
      ps -aux | grep emacs
      lsof -p PID | grep im-ibus.so
     -> grep found nothing.  in emacs -q , it can't input chinese.

   so, i go to download src from https://github.com/emacs-mirror,
   after the command  make   is done,
   i tried these command:
       ./src/emacs -q
       ps -aux | grep emacs
       lsof -p PID  | grep 'im-ibus.so'
   -> emacs PID  kevin  mem       REG              259,3    34688 1847459 /usr/lib/gtk-3.0/3.0.0/immodules/im-ibus.so
    -> 'im-ibus.so' it is there. and i can type chinese in emacs -q v29.


   i also tried to build:  https://ftp.gnu.org/gnu/emacs/emacs-27.2.tar.xz
   with emacs -q, it can't input chinese using ibus,
    and found nothing when use command:
        lsof -p PID  | grep 'im-ibus.so'.


but there still with two problem
 (1). i found the menu is moved with cursor blink,
    this short video is show what i say:
   (
    https://drive.google.com/file/d/18ynnH5Zvv3C87JMqXumNFhwobgjiP3sC/view?usp=sharing
    https://drive.google.com/file/d/16ghBGnQT8i03M3vxg456ZjyAAZMs665o/view?usp=sharing

   one is no candidate word menu occur, in emacs 27 when swiched to ibus on and input.
   another video is about the menu blink.
   )

 (2). since emacs 26, when i run ibus -rx ,
      ibus only malfunction in emacs ,
      in other like firefox work as normal.
      so i have to restart emacs to make ibus re-active in emacs.


could you hint me how to solved (1) mainly?
because there are packages or configs in emacs 29 can't work
and the ibus menu blink when i type words in emacs 29 continuously using ibus-rime.
(normaly, it should just move one time by next char, not continuously
blink position when typing)

The problem with Emacs 27 has already been fixed in 28.  So the real bug
is with the candidiate area blinking.

Other programs such as Firefox typically use the GTK input module, while
Emacs uses XIM, which doesn't like it when the IM server restarts.

Does that only happen under Xwayland?  If so, set
`x-gtk-use-native-input' to t, which will let Emacs use the GTK input
module instead, and should resolve the issue.

Thanks.

I'm not completely certain if the problem is with Emacs or with
Xwayland, so I'd prefer to make sure before adding it to etc/PROBLEMS.

For me it happens on X (GNU/Linux, default GTK build). I believe
bug#53172 is the same issue, maybe others.

The problem with that option is that it apparently breaks some key
modifiers, e.g. with x-gtk-use-native-input non-nil it becomes
impossible to bind C-S-u (Emacs processes it the same as C-u).

AFAICT, X input has been broken (or rather, you get to pick: either you
get working IME (with x-gtk-use-native-input non-nil), or working
modifier keybindings (with it being nil); but given that
x-gtk-use-native-input defaults to nil, for many/most people IME will
just stop working; also, it's not just IMEs like fcitx or ibus,
XkbLayout switching has the same problem) since the commit that
introduced the option (bisected yesterday):

Yes, the problem is the same as on the PGTK port, since both use the
same input method system.

It works here for me (Fedora 35, stock GNOME with IBus), but we do want
to fix this problem and keep X input methods working as well as they
used to.

Do you see the same problem in other programs that use XIM, such as
xterm?  If not, try placing:

  Emacs.inputStyle: none

in your X defaults file, and see if that solves the problem.

Most of this is caused by a more fundamental problem: XIM is an obsolete
interface with many limitations; most applications today rely on the
authors of input method frameworks to provide input modules for their
specific toolkit, and as a result the XIM backends for input method
frameworks get very little testing and are buggy.

Unfortunately, since we cannot demand that input method frame developers
provide modules specifically for supporting Emacs, the only choice we
have is between using the legacy interface standard to X (XIM) or the
toolkit's input method system (GTK native input), each with its own
limitations and advantages.

It's a sad situation, but there's nothing we can do.

Are you sure that's the commit which introduced this bug, and not one of
the preceeding commits that added features to the XIM support?

I find that hard to believe, since it doesn't touch anything related to
XIM.

Thanks.

This was supposed to say "framework".

If the same problem exists in xterm, it's plausible that IBus broke
their XIM backend, which shows up in bleeding edge GNU/Linux
distributions such as Arch.

It doesn't (see my previous reply). And I use fcitx, not IBus, but I
guess that doesn't really matter (as I wrote, even XkbLayout switching
is broken in the same way, _in Emacs_).

I don't use any desktop environment, just plain X.Org (with XMonad on
Arch Linux).

No, it continues working everywhere as before (including xterm), with
the exception of Emacs.

It does not (no observable effect).

Yes.  My git-bisect(1) invocation was

  git bisect start 3dfefb8bb4d9 041fff3d3dda

and given the interactive nature of the issue, I watched IME/XkbLayout
switching break and work again repeatedly while jumping around the
commit. The preceding 63c83e4 does not exhibit the issues.

Thanks, that is odd.  Could you give master a try to see if it's been

Yes, as of

commit 748eb32cc5e3
Author: Po Lu <luangruo@yahoo.com>
Date:   Fri Feb 4 09:04:06 2022 +0800

    Try to fix input method flicker on GTK builds

all seems back to normal: IME and XkbLayout switching works, as well as
binding C-S-u separately from C-u. (That's with x-gtk-use-native-input
at its default nil value; with it set non-nil, XkbLayout switching still
works and C-S-u is still separate from C-u, but I am unable to activate
the IME (fcitx) in Emacs; I'm not sure that is a problem, though: all I
wished for was for the former to continue working.)

Thanks!

Thanks, the problem with `x-gtk-use-native-input' should be fixed now as
well.

aiselcce@outlook.com, could you verify that the issue has been fixed for

Unfortunately, as of

    Make Emacs build with some other XLib implementations

it's a mess again.

Steps from emacs -Q -r:

1.
fcitx and XkbLayout switching works
(global-set-key (kbd "C-S-u") #'ding) "works" (separate from C-u)

2.
(setq x-gtk-use-native-input t)
C-S-u becomes C-u
fcitx and XkbLayout switching still works

3.
(setq x-gtk-use-native-input nil)
C-S-u becomes separate again
fcitx and XkbLayout switching breaks (the flickering issue again)

toggling x-gtk-use-native-input now again goes back to state 2., 3... ad
infinitum, state 1. (which is the one we/I want) seems unattainable at
this point.

That's a known problem, you have to move the input focus out and in the
current frame before the `x-gtk-use-native-input' setting can take
effect.

I will fix it later today.

Should be fixed now, please test.

    ; * src/xterm.c (x_alloc_nearest_color_1): Remove extraneous code.

using the testing procedure described in my last message, the only issue
that remains is that with x-gtk-use-native-input non-nil C-S-u becomes
C-u. The other issues seem to be fixed (i.e., resetting
x-gtk-use-native-input back to nil returns to the initial fully
functional state).

That's unfixable, it's a limitation of most GTK input modules.

Great, thanks for testing.
