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.)
