[Fedora-i18n-bugs] [Bug 1605054] New: Cursor becomes invisible in gnome-terminal after typing with ibus
by bugzilla@redhat.com
https://bugzilla.redhat.com/show_bug.cgi?id=1605054
Bug ID: 1605054
Summary: Cursor becomes invisible in gnome-terminal after
typing with ibus
Product: Fedora
Version: 28
Component: ibus
Severity: medium
Assignee: tfujiwar(a)redhat.com
Reporter: vtgoal(a)gmail.com
QA Contact: extras-qa(a)fedoraproject.org

Description of problem:
After typing in gnome-terminal with ibus input methods, cursor can becomes
invisible which is very inconvenient.
Version-Release number of selected component (if applicable):
Fedora 28 workstation x86_64
ibus-1.5.18-5.fc28.x86_64
ibus-libpinyin-1.10.0-1.fc28.x86_64 (or other Chinese input methods like
ibus-rime)
How reproducible:
100%
Steps to Reproduce:
1. Add Chinese (Intelligent Pinyin) as an input sources in Settings -> Region &
Language.
2. Open gnome-terminal
3. Switch to pinyin input (by press "Super" + "Space")
4. Typing, like "ceshi" to get the candidate words, Note: don't press "space"
to input a word, just stop at the list candidate words.
5. Press "Super" + "Press" to switch to another input method.
6. Now, in gnome-terminal, the cursor is disappeared.
This is one of the reproduce methods, switching to other windows while typing,
deleting all inputted letters while typing, may also trigger this. And this is
not limited to ibus-libpinyin only, other input methods like ibus-rime can
trigger this too.
Actual results:
Cursor in terminal disappears.
Expected results:
Cursor won't disappear.
Additional info:
From the same gnome-terminal tab, switch to Chinese input method, typing and
input a Chinese word can get the cursor back.
