Thanks for filing the issue!

Unable to reproduce the issue on reported chrome version 69.0.3472.3 using Mac 10.13.1 with the below mentioned steps.
1. Launched Chrome
2. Inspected a page to open DevTools
3. Undocked DevTools
Observed the mouse working fine without having to click anywhere. Attaching the screen cast of the same.

@Reporter: Could you please have a look at the screen cast and let us know if we have missed anything in the process. Any further inputs from your end may help us.

@Reporter: Your screencast(...comment#5) explaining the mouse cursor misplacement was very helpful in understanding the issue being faced by you, besides we were unable to reproduce it from our end i.e., the mouse cursor placement was proper when hovered on undocked DevTools. Could you please check the same in a new profile with out any apps & extensions and let us know if the issue still persists. It would also be helpful in mentioned whether similar issue is being seen on other machines too...!

Thanks!

I can confirm that in a new profile I CAN'T reproduce the issue.
I don't know what extension/app or setting could be doing this, but I'm pretty sure this did't happen before I update to latest version, and I had the same extensions/apps or settings.

Ok, I disabled all extensions in MY profile and the issue is gone. So maybe now I have to identify what extension is causing the issue, I have some extensions that I don't use anymore so maybe I need some clean up :(

@Reporter: From your comment#10 it is clearly understood that the issue isn't with chrome rather it's with any of the installed extension(s), so could you please let us know if we can close this issue!

Thanks!

This is triggered by any extension that adds to the Chrome devtools, such as HTTPS Everywhere, or React Developer Tools.

Yes, I can confirm that. I turn on React Developer Tools and I have the issue. Well...

You are probably looking for a change made after 563000 (known good), but no later than 563011 (first known bad).

(Performed this bisect with `--enable-features=ViewsBrowserWindows`.)

I can't reproduce this, but perhaps its as I do not have ViewsBrowserWindows on.

+ccameron, as https://chromium.googlesource.com/chromium/src/+/6be8acd7b09a2378d8c47ca9fa91b9fd9b4839ba looks like the culprit.
+dgozman, in case you've seen something related

thanks very much for the investigation, jleedev!
and thanks for the details and video, franco.

The issue seems to be with an extension rather than with chrome(...as per comment#8, #10) and the CL is provided in comment#15, hence removing Needs-Bisect label, please feel free to add the label back if required.

Thanks!

Thanks, I can reproduce this now. It reproduces in MacViewsBrowser as well.

Disabling ng-inspect-for-angularjs solved the issue for me. This is another extension that adds a sidebar pane to the elements panel.

This is fixed in latest version (70.0.3499.0).

The latest version fixed the "unlock into separate window" situation, but it still has the issue on "dock to bottom", "dock to left" and "dock to right"

Fix typo causing warped mouse input

This function was computing the right transform, and then applying it

Is there any idea on when 70.0.3501 will be released?
