Description Jens Petersen 2018-12-11 12:34:53 UTC
Description of problem:
I was testing Ctrl-Shift-e emoji/symbol input and scrolling through
the long candidate list eventually cased my gnome desktop session to hang
completely.

Version-Release number of selected component (if applicable):
ibus-1.5.19-9.fc29

How reproducible:
This has happened to me at least 2 times now.

Steps to Reproduce:
1. I tried to input some arrow symbol:
2. Ctrl-Shift-e arrow SPACE
3. Keep scrolling through the long list of candidates.
4. Move the mouse pointer and/or Esc out of the pre-edit.

Actual results:
Desktop eventually hung hard. It was on candidate 242/645.

Expected results:
No hang or crash.  Escape from input normally.

Additional info:
I had to powercycle my laptop (ie forced reboot) to get my desktop back.

This message is a reminder that Fedora 29 is nearing its end of life.
Fedora will stop maintaining and issuing updates for Fedora 29 on 2019-11-26.
It is Fedora's policy to close all bug reports from releases that are no longer
maintained. At that time this bug will be closed as EOL if it remains open with a
Fedora 'version' of '29'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 29 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

Not so easy but I can still reproduce on F35.
Basically had to hold down the PageUp key on the candidate window.

Comment 3 Jens Petersen 2022-10-17 06:37:05 UTC
(I tried to reproduce this today in F35/F36/Rawhide vm's, but so far could not)
I can't reproduce on my F36 laptop, hope I am not missing something.
