My feedback report is at http://listnr/product/5015361/report/80536950750, although I didn't see anything relevant in the Chrome user log when I checked right now.

->khmel@ who worked on shortcut support for ARC++

ARC++ creates a window for system related windows, which is invisible by default, and I'm wondering if it has something to do with this.

+ afakhry@ who is the owner of ash accelerator.
+ mustash folks in case there was a known regression on (m)ash side.

I have seen this as well, on a corp enrolled samus.

mustash did refactor this to use a mojo interface from ash to chrome, but that landed ~11 months ago.

+yhanada who did some recent work for android shortcuts.

I'm seeing this again almost immediately on the same device after signing out and back in. What's the plan for tracking down the cause?

Increasing priority, as this is an annoying bug that's present on the stable channel and potentially affects many users.

So far I cannot reproduce. I tried different builds, enrolled and not, mp-signed and test images. It  works stable to me. I also traced event dispatching but did not find and suspicious.

Do we have more-less reliable steps to repro? Can be reproduced on test image?

The usual workflow under which I've seen this is:

1. Sign in to google.com account.
2. Sign in to gmail.com account as well.
3. Use both accounts for a while (without opening any Android apps).
4. At some point, notice that global accelerators stop working on both desktops unless there's at least one window open.

I tried to repro this just now on a recent eve dev build (using two test accounts), but the problem hasn't shown up yet.

Is there anything I can do to get more info the next time I see it?

Thanks Daniel, I will try to use your scenario intensively. So far there is nothing special to look up, only if you find some regularity.

To confirm, your scenario does not involve multi-profile configuration (primary + secondary profiles) and you just sign out one and sign in another account.
Both accounts have ARC running.
Right?

This *does* involve multiprofile. I think I've only seen the bug on this eve device running 62, and it's always logged into both my google.com and gmail.com accounts.

I don't think I've seen the bug on a caroline device that's also logged into both accounts, but it's still using 61.0.3163.123, so that's a useless data point if this is a regression in 62.

Re "both accounts have ARC running", don't we only allow ARC to run on the primary account (i.e. google.com, in this case) right now?

#11, Yes we use only primary account. Thanks for update

This definitely happens inconsistently. I've been using the same system (now on 62.0.3202.82) with the same two accounts logged in for a few days and haven't re-encountered the problem yet.

Earlier, I had rebooted while still on 62.0.3202.74 and saw the problem again almost immediately.

I've just heard about this problem on Eve for just one public account. Trying to find repro on that device.

It's been a long time since I've seen this, but it's happening again on a different device right now:

Google Chrome	63.0.3239.140 (Official Build) (64-bit)
Platform	10032.86.0 (Official Build) stable-channel caroline

On my gmail.com account, I don't have any windows open and I'm unable to use Ctrl+N, Ctrl+Alt+Comma, etc. As soon as I open a window, those accelerators start working.

On my primary google.com account, I have this window open and am able to use global accelerators.

I'm hoping this is  issue 780146 . I'll undupe if I still see it in M65.
