Steps to reproduce the problem:
Not sure if this will reproduce:

1. On Ubuntu 16.04 with xfce, `apt-get install --no-install-recommends ibus-gtk ibus-gtk3 ibus-qt4 ibus-mozc mozc-utils-gui`, set up ibus and mozc, switch to Japanese with input mode Hiragana.
2. Set DPI to 165 in xfce settings
3. Start Chrome
4. Type into the address bar and notice how the IME suggestions pop up in the wrong place.

What is the expected behavior?
IME pops up in the right place.

What went wrong?
IME pops up in the wrong place, as if Chrome is telling ibus the wrong coordinates that don't incorporate the scale factor that Chrome is using.

Did this work before? N/A 

Chrome version: 51.0.2704.63  Channel: stable
OS Version: Ubuntu 16.04
Flash Version: Shockwave Flash 21.0 r0

This appears to only affect Chrome; the IME box pops up in the right place when using other applications.

It pops up in the right location if I start Chrome with --force-device-scale-factor=1.0.

This worked fine a few days ago, but no longer works for reasons I don't know.
