Interim solution

(setq wl-copy-process nil)
(defun wl-copy (text)
  (setq wl-copy-process (make-process :name "wl-copy"
                                      :buffer nil
                                      :command '("wl-copy" "-f" "-n")
                                      :connection-type 'pipe))
  (process-send-string wl-copy-process text)
  (process-send-eof wl-copy-process))
(defun wl-paste ()
  (if (and wl-copy-process (process-live-p wl-copy-process)) nil
    (shell-command-to-string "wl-paste -t text -n 2>/dev/null")))
(setq interprogram-cut-function 'wl-copy)
(setq interprogram-paste-function 'wl-paste)
(setq confirm-kill-processes nil)

WIth clipboard, it does not reproduce.
WIth kill-ring, it reproduced.

not clipboard issue, but kill-ring issue?

[kekeimiku]

Yes, is kill-ring issue...

[masm11]

I fixed it in feature/pgtk on savannah. Please try it.

[kekeimiku]

It is indeed fixed in emacs,but there is still a problem.
When I copy unicode from emacs to chrom(e)ium

I currently only find chrom(e)ium has problems

Don't think this is an issue from Emacs side. If you input some CJK
using Firefox(which runs naively under wayland), then copy/paste
it into Chromium. Same issue. @Makima0

You can using Chromium extensions like atomic-chrome
or Edit with Emacs to input CJK for now.

I can copy normally from alacritty.

(setq wl-copy-process nil)
(defun wl-copy (text)
  (setq wl-copy-process (make-process :name "wl-copy"
                                      :buffer nil
                                      :command '("wl-copy" "-f" "-n")
                                      :connection-type 'pipe))
  (process-send-string wl-copy-process text)
  (process-send-eof wl-copy-process))
(defun wl-paste ()
  (if (and wl-copy-process (process-live-p wl-copy-process)) nil
    (shell-command-to-string "wl-paste -t text -n 2>/dev/null")))
(setq interprogram-cut-function 'wl-copy)
(setq interprogram-paste-function 'wl-paste)
(setq confirm-kill-processes nil)

If you change the default interprogram-cut-function and interprogram-paste-function of emacs to wl-clip, everything returns to normal.
So I think it’s an emacs issue.

[declantsien]

Nice. Indeed it works. @Makima0

Side question. Which input method software are you using
when input CJK characters on alacritty?
I can't active fcitix 5 on alacritty nor chromium.

[masm11]

@Makima0
It does not reproduce with emacs -Q.

Please tell me:

• version of gtk
• version of chromium
• window manager and its version

gtk3
sway version 1.5.1
Google Chrome 88.0.4324.146

[masm11]

I installed sway 1.5.1 and downgraded chromium to 88.0.4324.146, but the issue does not reproduce.

What OS do you use? And what is its version?

[kekeimiku]

I use the latest Arch Linux.
Use this flag to ensure that chrome runs on Wayland.
--enable-features=UseOzonePlatform --ozone-platform=wayland
I guess you are using xwayland to run chrome?
If you use xwayland , this problem will not occur.

[masm11]

Thanks for the OS and version.

chromium on wayland?? I didn't know such a thing...
ok, I'll try it tomorrow night.

[masm11]

confirmed.

[masm11]

Run gtk3-demo, double-click Entry Buffer in Entry, input a unicode string in the entry buffer, and copy and paste it to chromium.
The same issue reproduces.
Maybe it is gtk's issue or chromium's issue.

I'll look for a work around.

[masm11]

@Makima0
Fixed in feature/pgtk on savannah. Please try again.

[kekeimiku]

@masm11 The issue has been fixed, thank you very much!

[declantsien]

I have problem yanking text from Chromium
Select some text from Chromium(wayland and xwayland) and copy C-c. Open PGTK Emacs, hit C-y.
Copied text is not there.
Can you guys verify this?
@masm11 @Makima0

[masm11]

@declanqian reproduced.

[masm11]

@declanqian I'm debugging.
This should be a work around until fixed:

(setq x-select-request-type '(UTF8_STRING COMPOUND_TEXT STRING text/plain))

[masm11]

@declanqian Fixed in feature/pgtk on savannah. Please try it.

[declantsien]

Cool, it's working. @masm11
