+ellyjones@, could this be M69 stable blocker as it was also highlighted in internal mail thread "Chrome M69 Day 1 - gUP User Feedback Launch Report"?

I am working on the fix

Reset toolbar style when exiting tab fullscreen mode

On Mac, tab fullscreen mode doesn't show top UI while browser fullscreen
mode may show top UI depending on user's preference. When Chrome exits
from tab fullscreen, it needs to reset the top UI style to the one
corresponding to browser fullscreen. In addition, if it exits from tab
fullscreen to browser fullscreen, a re-layout may be triggered if top
UI needs to be shown.

This CL fixes the problem by calling UpdateUIForTabFullscreen() when
Chrome exits tab fullscreen, no matter it is going back to browser
fullscreen mode or normal state. So it can update the top UI status
correctly.

This CL also adds reading initial toolbar style value from user
preference.

Sounds like we should try to merge to 69 and take this in the respin.

I will first wait for tomorrow's canary to confirm the fix.

Handle exiting tab fullscreen by clicking traffic light button

Usually, user exits tab fullscreen mode by clicking 'ESC' button as
suggested by exit bubble on Mac. However, during tab fullscreen user
can still click the green traffic light button from the slide-down
system menu to exit fullscreen. In this case, the toolbar style has to
be updated as well.

This CL fixes this by calling UpdateFullscreenTopUI() from
BrowserNonClientFrameViewMac::OnFullscreenStateChanged() where all the
transitions from fullscreen to non-fullscreen mode would pass through.

 Issue 876708  has been merged into this issue.

The bug OP originally reported was fixed on 71.0.3545.0, and confirmed.

This fix caused another regression for me:  Issue 884029 .

 Issue 885275  has been merged into this issue.

This issue is NOT fixed on my Mac in Chromium build 71.0.3558.0 or Chrome Canary build 71.0.3557.0.  The issue persists, exactly as already described here.  I cannot access the tool bar in full screen mode without using the "Always Show Toolbar in Full Screen".

I'm just a random end user in the workplace who suddenly discovered that Chrome is now broken in several key ways, including this one.  And now I'm going to have to manually downgrade to an old version simply to do my work.  Please do better QA before you unleash broken browser updates on millions of people all over the world?  Chrome 69 never should have been released.

Re. #18, that's tracked as issue 868398.

Issue remains on Mac

Re #20, we fixed on 70.0.3538.17 and later. It is in Beta, will take a few weeks to reach stable.

This problem is STILL not fixed. Are users waiting on a new Google Chrome version update?

I will try to manually downgrade to an older version of Google Chrome. Disappointed.

#23: What version do you still see this issue in? Is it older or newer than 70.0.3538.17?

#24: I just updated to Chrome Version 71.0.3578.44 (Official Build) beta (64-bit) on a MacBook Pro and the problem is still there.

#25: Thanks - reopening.

I changed the title to clarify that this bug is about showing tab strip in regular browser fullscreen after exiting fullscreen video playing. Please see the video OP posted.

If you are expecting to see the tab strip from slide-down menu without always showing tab strip in fullscreen, that is tracked at issue 868398.

Feel free to file a new bug if neither of these apply to your case. thanks.

#27: Sorry, I made a mistake about which issue is which. This issue is in fact fixed as I followed the steps to reproduce the issue as described at the top, so I can confirm that on Chrome 71.0.3578.44, this issue is fixed.

I was talking about the tab strip not showing when Always Show Toolbar in Full Screen is not toggled and the mouse is moved to the top (which results in a grey tab with the traffic light buttons showing up, but not the expected tab strip) which is described in issue 868398.

Re: #28, no problem. Thanks for the confirmation. Let's close this bug then.

The Issue 868398 discussion board won't allow me to comment on it due to restricted access. If Issue 868398 is the problem I have described, how can I let it be known that Issue 868398 is not fixed yet?

#30: You can't - but as the bug is still marked Assigned (not Fixed) we are already aware that it is not fixed yet.

Issue still persists - I've been having it starting today with the latest update of chrome ..

#32: What version of Chrome are you still seeing this in?

Still broken in 72.0.3626.64...keep installing updates expecting some sort of movement but nothing for months.
