Problem Description

Chrome doesn't support IME under native Wayland before ver 98, and IME only works if gtk-version=4 is enabled after. However when I pass that flag to electron, it would crash saying GTK 2/3 symbols detected. Using GTK 2/3 and GTK 4 in the same process is not supported

Proposed Solution

No idea

Alternatives Considered

No idea too

Additional Information

No response

For reference: IME refers to something like ibus or fcitx.

I'm working on implementing text-input-v3 to chromium. This issue could be solved with this patch.

@OctopusET Just to understand what the stand is on Electron/Wayland. Would this patch solve the issues I've listed in this Phosh/squeekboard thread:

https://gitlab.gnome.org/World/Phosh/squeekboard/-/issues/244#note_1581502

[OctopusET]

As far as I know, yes.
Sorry for delays, I didn't have extra time. I think I can restart work soon,

[Silentdoer]

hi, this bug has been fix?

[OctopusET]

@Silentdoer Not yet, I'm currently working on now.

[stalkerg]

@OctopusET do you need help?

[OctopusET]

@stalkerg not now, but could you test it later?

[stalkerg]

@OctopusET sure, one more question - is your chromium patch dependent on gtk4?

[OctopusET]

no it isn't. GTK4 dependent patch is already there.

[stalkerg]

It should be mentioned #33690 here, as I understand, no?

[OctopusET]

@stalkerg chromium source has gtk4 patch but I think it hasn't enabled on electron.
And this patch has some own bugs.

Just realized that KWin has got text-input-v1 support recently which makes input methods work in Chromium and Electron apps. (https://invent.kde.org/plasma/kwin/-/merge_requests/3403)

[stalkerg]

@AllanChain is correct, and it's good, but it's anyway "deprecated" protocol.

[Silentdoer]

hello, can I ask how you're processing at the moment?

[buresu]

In my environment (KDE Plasma 5.27.10 and fcitx5 5.1.7), the following flag works through text-input-v1.

--enable-wayland-ime

[Kimiblock]

While Kwin supports text-input-v1, the majority of compositors support the v3 variant

I'm using Gnome and iBus. In Flatpak Chromium putting gtk-version=4 still couldn't get IME working.

Try GTK_IM_MODULE=xim XMODIFIERS=@im=ibus google-chrome --gtk-version=4, this works for me.

Didn't work for me unfortunately. This might be a Flatpak specific issue.

[C0rn3j]

@sith-on-mars you can probably put a chromium-flags.conf somewhere into your Flatpak with your desired flags.

@forza91 just in case - IME input for VSCode not working even under KDE.

No, bro. Fcitx5 works in KDE Plasma 5.27 with virtual keyboard is on. Native wayland vscode. You can check the previous comment in this thread
