Description of problem: In Fedora 33 Workstation, with a Chinese system language, when I try to input with the ibus input (intelligent pinyin), and I pressed the slash key'/', then the slash character '/' will automatically keep repeating itself, even if I only pressed the slash key '/' once. Not only this caused unwanted '/' to spam, but: 1. Also prevents me from pressing alphabetical characters to use pinyin input normally, unless I delete all my remaining characters to exit pinyin prompt and start over; 2. Can possibly delete my already-saved text, in combination with <Ctrl-Backspace>. It seems that I have completely lost control within the pinyin prompt. I have met with other surprising conditions, though cannot be immediately reproduced now, but I believe more combinations of inputs triggering different bugs will be confirmed later. Version-Release number of selected component (if applicable): Any kind of version. I also tested with Fedora 32 Workstation, still have this bug. How reproducible: Always Steps to Reproduce: 1. Fetch any Fedora Workstation version, be it 32 or 33 or any updates applied. 2. Add Chinese input method 'Intelligent Pinyin' and switch to it 3. In GNOME(Wayland), open any GTK-based application, be it Firefox, GNOME Terminal, gedit, Libreoffice, ... (take gedit as an example) 4. Input 你好，今天天气 (keypress: nihao<1>，jintian<1>) as a start up example, confirm input use number key '1'. or keys like <Enter> or <Space>. 5. Input 怎么样/ (keypress: zenmy/）. Do not confirm immediately after 'zenmy', but press '/' exactly once. 6. The '/' character is repeating itself within several hundred milliseconds. 7. Press <Ctrl-Backspace>. gedit will highlight "你好，今天天气" (with a lot of trailing '/'). 8. Press <Backspace> to delete these Chinese characters. Actual results: Not only '/' is repeating itself, but also I lost control to gedit and gedit thinks you want to press '/' forever or even wants to delete my already-confirmed characters before this input. Expected results: 1. '/' Should not trigger anything, unless I have pressed this key and did not release this key press (but I always release keys) 2. '/' Should not make me lost control over pinyin prompt to gedit 3. <Backspace> Should only delete pinyin alphabets in pinyin prompt panel, and should not do anything to the background gedit texts, unless I have exited the pinyin prompt panel (because I confirmed my input or have deleted every pinyin alphabet in it) Additional info: 1. I did not found this bug on Debian buster or Arch with latest updates. Additionally, '/' did not even input a single character '/' in these distributions, but I cannot confirm if this is the expected behaviour. In Fedora 33 KDE, '/' did input a single character '/', but immediately stopped. 2. I didn't find this behaviour in qt-based applications (like Fedora Image Writer or Octave) in GNOME, or any application in other desktop environments (including KDE, or even GTK-based Cinnamon Desktop). This bug seems to only occur on GTK-based applications on GNOME. 3. I can be very sure that this is not caused by something wrong with my specific keyboard, because (a) Other distributions worked very well (b) Other Fedora spins worked very well (c) Qt-based applications in GNOME worked very well (d) GNOME X11 session worked very well (e) I replicated this bug on a fresh install of Fedora 32 Workstation in another laptop of mine. 4. I guess other special characters (or keys) like '[', ']', '\', '<Esc>', '<Backspace>', etc. may trigger similar bugs, but I cannot confirm. '/' will surely trigger this. ',' and '.' are used in pinyin input method to flip candidate characters pages, so they doesn't trigger this bug. ' does not trigger this bug (used in xi'an for 西安)
This bug doesn't seem to affect KDE, no matter it's a Wayland session or X11 session.
In short, it's a very subtle bug, which only affect "Fedora Workstation's GNOME Wayland session and GTK-based applications", not anything else. I have been deeply confused about this, ONLY the combiation will trigger this bug.
(In reply to Yang Wentao from comment #1) > This bug doesn't seem to affect KDE, no matter it's a Wayland session or X11 > session. My mistake, I test for Plasma(Wayland) again and on wayland session ibus-libpinyin simply does not work entirely. It does displays an icon, but nothing afterwards. Looks like this bug may also be wayland-related.
Could you try to test the pinyin input method with new user account or with Fedora Workstation Live iso?
(In reply to Peng Wu from comment #4) > Could you try to test the pinyin input method with new user account or with > Fedora Workstation Live iso? I tried the pinyin input method with a new user account on my existing fedora installation, and I also tried the pinyin input method with a Fedora Workstation 33 Live iso (which is possible, because GNOME settings allows you do that even in Live iso). This bug still persists.

I think this bug is improved in Fedora 39.
Is this still happening on any of F38+ releases?
