wrong display when toggle device toolbar on two monitors(a hidpi and a non-hidpi monitor)

Reported by han.guo...@gmail.com, Mar 12 2018

Issue description

UserAgent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_3) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/65.0.3325.146 Safari/537.36

Steps to reproduce the problem:
1. use two monitors, one normal(non-hidpi) monitor, one hidpi monitor(eg, use 1280x720 hidpi resolution on 2K monitor).
2. put one web page on the normal monitor.
3. open that page's devtools window into a separate window and put this window on the hidpi resolution monitor.
4. click 'toggle device toolbar' on devtools
5. on normal monitor, the debug page just display 1/4 screen.

What is the expected behavior?
the page should display normally.

What went wrong?
separate devtools into another window and put two windows on two different monitors, if two monitors are different: devtools window on hidpi, web page window on non-hidpi, the web page display wrong. but put the web page window to hidpi monitor, it display normally.

Did this work before? N/A 

Chrome version: 65.0.3325.146  Channel: stable

han.guokai@ Thanks for the issue.

Tested this issue on Windows 10 on a normal monitor and a HiDPI monitor on the latest Canary 67.0.3368.1 and the reported version 65.0.3325.146 by following the below steps.

1. Launched Chrome on Normal monitor -> opened a webpage -> Opened Devtools in a separate window and dragged the devtools window to HiDPI monitor.
2. Set the resolution of the HiDPI monitor to 1280x720 and hit the 'toggle device toolbar' button on Devtools window.
Can observe the complete webpage on the normal monitor without any issues.

As this issue is reported on Mac OS, the dual monitor setup for Mac OS is not available at TE end to triage this issue. 
Hence adding TE-NeedsTriageFromHYD and requesting someone from Inhouse team to please look into this issue.

Thanks..

I also used the latest Canary 67.0.3368.1 on Mac to test. There is no this problem on Canary version. Also there is no problem before stable Chrome 65. So maybe it is fixed in latest version.

Add some details in my hardware environment.
1) Normal monitor: an old MacBook Pro(not retina), 1280x800 native.
2) HiDPI monitor: use 1280x720(HiDPI), which is 1/4 the monitor's max native resolution(2560x1440).

Tested in chrome # 65.0.3325.146, Stable #65.0.3325.162 & Canary #67.0.3369.0 on Mac 10.13.3 as per steps provided in comment #0 and not able to reproduce the issue.Screen is displaying properly.

@ han.guokai: Could you please create new profile without extensions and apps.Re-check once in latest stable #65.0.3325.162 and let us know the observations  of the issue which would help us to triage the issue further.

Thanks in Advance.
On 65.0.3325.146 with no extensions, it is the same problem here.

After I updated to Stable 65.0.3325.162, the problem disappear! It is display normally now.

Add an operation detail, although it's correct on the latest 65.0.3325.162, I use shortcut (Cmd+Option+I) to open DevTools window. Because chrome remember it's last option and position, it automatically open the devtool window on another (hidpi) monitor, not dragging it to there. Maybe this can reproduce on 65.0.3325.146.
