Current ibus-gtk4 not working correctly: gtk4 will become increasingly

    1.Install ibus-gtk4 and gtk4-devel packages.
    2.Enable an input method engine
    3.Run gtk4-demo
    4.Select "Entry" -> "Completion" in the left pane
    5.Click "Run" button in the top
    6.Focus on the input entry and type a language string.
    7.Try to press backspace.

   Backspace key does not working

Expected results:
   Backspace key should work

Thanks, Priyam

It seems related to the ibus-gtk4 immodule.
At least if I disable all IMEs or remove ibus-gtk4
then gtk4 input works normally again.

(I used Text View -> Multiple Views to avoid any other input completion feature.)

Comment 1 fujiwara 2021-08-19 09:27:08 UTC

I will rebase ibus to 1.5.25
The differences between the current RHEL9 ibus and 1.5.25:
1.  Enable sync process in GTK4 (this subject)
2.  Support set_surrounding_text with selection index
3.  Support include directive in the Compose feature
4.  Use · instead of ⎄ to display Multi_key in the Compose preedit
5.  Make Compose preedit less intrusive
6.  Enhance engine search function
7.  Support ClientDisconnectMode in ibus-x11
8.  Run ibus-daemon with the background from ibus-setup
9.  CI enhancements
10. Translation updates

Can be moved to #1995528

Comment 4 Priyam Gupta 2021-08-27 13:56:33 UTC
