After reinstall Chrome (the same Version) the emulated device view looked as expected. But when I switched to the responsive mode and changed the view size and after that switched back to the emulated device view, it looked the same as before in my screenshot.

Able to reproduce this issue on 65.0.3325.146 using Mac 10.13.3, but not reproducible(fixed) on latest canary 67.0.3364.0. Hence providing reverse bisect info. Issue is not reproducible on Linux and Windows.

Last Bad Build: 66.0.3358.0
First Good build: 66.0.3359.0

You are probably looking for a change made after 540146 (known good), but no later than 540147 (first known bad).

@ccameron: Please confirm the bug and help in merging to M-65 if it is safe. Adding RB-Stable for M-65. Please remove if not the case.

Thanks!

This is similar to  issue 817238 , but apparently the offending commit https://chromium.googlesource.com/chromium/src.git/+/e24c90e284ccaae925132cc0271d9179b5560ec3 was merged to 65 here: https://chromium.googlesource.com/chromium/src.git/+/64461531b578e20751309ffabcbe67493c934ced.

We should merge the fix from  issue 817238  (https://chromium.googlesource.com/chromium/src/+/615f354b286f4e9acdcc6c42fdb2dc640577640d) to 65. Fady, could you please check whether it's safe to merge and manually verify that everything works on the 65 branch? I am not sure how to check whether everything surface-related works fine.

This is reproducible on retina and non-retina Mac, and affects all DevTools users on Mac. Definitely a stable blocker.

The proper fix would be to merge https://chromium.googlesource.com/chromium/src/+/615f354b286f4e9acdcc6c42fdb2dc640577640d to 65. Unfortunately, that does not merge cleanly as there have been a couple of refactors since 65 in this area. fsamuel@ is working on an isolated fix.

I know it is early but requesting postmortem for this before I forget.

The following revision refers to this bug:
  https://chromium.googlesource.com/chromium/src.git/+/ed7c8bf8cf749050d4256ff7b597cfeaa219e12e

commit ed7c8bf8cf749050d4256ff7b597cfeaa219e12e

Devtools: Fix clipping with device emulation.

8bb58f52036793831d0363c285a6b159b21513d9 exposed a pre-existing bug on Mac
whereby an incorrect device scale factor was passed into the compositor
when device emulation mode was turned on. This bug only occurs on Mac
because Mac and Windows used different code paths for device scale factor.

Windows always reports to the compositor a device scale factor of 1, and then
passes the real device scale factor to Blink which deals with the scaling itself.

Mac reports the actual device scale factor to the compositor along with Blink.
Blink doesn't deal with the scaling directly via zoom.

In either case, device emulation can change the device scale factor. The DSF
reported to the compositor must be the non-emulated DSF. The pre-existing bug
was that we passed the post-emulation device scale factor to the compositor which
affected clipping.

Stupid question, where can I download the version 65.0.3325.150?
I use this page https://www.chromium.org/getting-involved/dev-channel and there I choosed "Beta channel for Mac". But there is still the 65.0.3325.124 Version.

Any estimated time about releasing .150 build? I'm still getting the .146 at 10:45 AM Spain local time when using standard browser version autoupdate
