Public bug reported:
OS: Ubuntu 17.10 (Linux weilong-Ubuntu 4.13.0-16-generic #19-Ubuntu SMP
Wed Oct 11 18:35:14 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux)
GNOME version: GNOME Shell 3.26.1
Chrome version: Version 62.0.3202.75 (Official Build) (64-bit)
Description:
This may very likely have something to do with my Chinese input method
(iBus). I encounter this consistently while the system input method is
Chinese (WubiHaifeng86) but the mode within the input method is English.
Inputting in Chrome URL bar is triggering UI freeze and major memory
meak. The whole UI freezes and won't respond to either mouse or
keyboard. Can't switch to console by Ctrl+Alt+Fx. Was able to ssh in
from another machine and gather information.
Reproduce Steps:
1. Switch system input method to Chinese (WubiHaifeng86)
2. Switch to English inputting mode (while system input method is still
Chinese).
3. Open Chrome
4. Input some characters in URL bar and the bug should occur. If not, use
Backspace to delete some and input some more.
(Sometimes swapping step 2 and 3 might help reproduce the issue.)
