UserAgent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/53.0.2785.143 Safari/537.36

Steps to reproduce the problem:
1. Start X on VT1 and open a Chrome session.
2. Start another X on VT2 and try to open a Chrome session.

This doesn't work even when using --user-data-dir without value to force a new session.

What is the expected behavior?
Chromium opens on the X running on VT2.

What went wrong?
Chromium opens on the X running on VT1.

Did this work before? N/A 

Chrome version: 53.0.2785.143  Channel: stable
OS Version: 4.7
Flash Version: Shockwave Flash 23.0 r0

This requires weird workarouns like [1]. Respecting the $DISPLAY variable is part of complying with the X specification and Chromium violates this.
