Draggable image displaced a little on laptop display but not on extension display

Reported by mrajen...@vdmbee.com, Aug 14 2017

Issue description

UserAgent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/60.0.3112.90 Safari/537.36

Steps to reproduce the problem:
1. Please have look at this URL to test drag and drop 
https://html5demos.com/drag/#

when the draggable div are selected and just started to drag the image gets displaced to the right on a laptop display, try to do the same on an extension display and you will not find this... The same works well with IE on both displays.
The problem with that is when we do drag and drop the drop of ghost image is displaced a little bit from the position it is actually dropped. 

2. 
3. 

What is the expected behavior?
The image should not have displaced when beginning to drag. So if we on drop place the image at point of drop, it actually again gets displaced.
The dropped image should be placed at the same point its is dropped in a laptop display.

What went wrong?
When the image dragged on a laptop display it gets displaced by a small distance.... 

Did this work before? No 

Does this work in other browsers? Yes

Chrome version: 60.0.3112.90  Channel: stable
OS Version: 10.0

mrajender@ Thanks for the issue.

Unable to reproduce this issue on Windows 7 and Mac OS 10.12.6 with latest stable 60.0.3112.101 and Canary 62.0.3192.0 with the below steps.

1. Clicked on the above given link after connecting the system to extension display.
2. Dragged the image and dropped the image and could not observe any displacement of the image when beginning to drag on laptop screen and as well on extension screen. 

Could you please provide us with the screen cast where you are seeing the issue for further investigation.

Regards,
Susan 
Please have a look at the recording attached (play with windows media player)..I actually just select and just move 1mm length but you see the image displayed much further..
I do the same on my extension display and you can see the difference

After watching the extensiondisplay.avi, it looks like chrome and windows disagree about the location of the pointing. The cursor appears several hundred pixels off to the right of where chrome perceives it to be. The mapping of the mouse position into the viewport's coordinate system in borken for some reason?

This doesn't looks like a d-n-d issue, the pointing device is confused on the secondary display, reassigning components accordintly.

I don't have a laptop, I have a two monitor win10 desktop with both monitors attached to a single nvidia gpu. The problem does not repro on this desktop system.

mrajender@ could you describe your hardware setup a little more, you have a laptop with a external monitor, is that right? What kind of laptop, what kind of gpu, and what kind of port are you using for the external monitor? Are you mirroring the main display on the secondary display or are you extending the desktop to span both displays? Thnx.

Dont worry about the mouse position as that was introduced by the software I used to create the recording.Please have a look at lt.avi recording and compare the image displacement... as compared to one in the extensiondisplay.avi. You will need a laptop to reproduce it..I use a Dell inspiron 15 7000 laptop.

Tested this issue on Windows 10(Lenovo Thinkpad laptop) with chrome #62.0.3202.89 and observed that on  the dropped image is placed at the same point where is dragged on display.

mrajender@ For further triage could you please help us with screen-cast of IE browser, to know the good behavior of this issue.

Thank You...

Hi, I have also tested on lenovo... this works fine on it. But with Dell laptops the drag imae is displaced.So This is a dell display specific issue on chrome browser. Can you please re-test on a dell laptop?

Thanks and Regards
