HighSierra: At times 'gmail.com' is not loading.

Project Member Reported by manoranj...@chromium.org, Jul 6 2017

Issue description

Chrome: 61.0.3150.0 Canary
OS X: Mac OS X 10.13 Beta (17A291m)

1. Launch Chrome browser
2. Try to access gmail.com by clicking 'Enter' at the end

We are seeing blank page instead of gmail login screen. This is not consistently reproducible, however i do see this issue couple of times a day.

Attaching the screen-cast for your reference.

Thank you!

Hi manoranjanr@ - are you running 10.13 in a VM or actually installed on a machine?

It's not a VM and i've local machine with the set-up!

Thank you. I upgraded my Touch Bar Mac to 17A291 but cannot reproduce.

ccameron@ - any thoughts?

ccameron@ - gentle ping. What are your thoughts on what's happening here.
I don't see anything suspicious off the top of my head.

That said, it looks like you're opening a gmail authentication window, which sometimes causes an iGPU->dGPU switch (shouldn't, but does) -- does this reproduce if you force usage of the iGPU via gfxCardStatus? Try also with the flags individually.
  --disable-remote-core-animation
  --disable-gpu
Oh and one more set of flags
  --disable-mac-overlays

Do you mean you experienced the issue in 61.0.3159.0 while running with the flags?

Nope, i was seeing this issue without any flags.

[mac triage] this does seem like ccameron's bailiwick - some kind of GPU interaction. Possibly something Apple need to iron out. But we can't do much without a reliable repro. I couldn't repro it.

But if we possibly *can* repro with any of --disable-remote-core-animation or --disable-gpu or --disable-mac-overlays individually, then that could rule out the above and suggest a different issue.
It looks like manoranjanr@ is in MTV. Perhaps ccameron@ you can sync up with manoranjanr@ when you're in MTV next week?
There's a similar issue filed in  issue 745872 .

If we don't have a reliable repro for this, it will be nearly impossible to make progress on. I haven't changed anything in compositing in almost a year at this point.
It sound like manoranjanr@ can repro it reliably.
I'm not going to be in MTV for the next >1 month -- maybe someone in MTV can take a look?
This also sounds similar to  issue 749438 , which has managed to be reproduced.
hmm.. one more scenario attached here. The strange thing here is repro is not consistent and based on my 2 cents it happens on certain newly opened websites which never have been browsed on this machine (preferably after OS upgrade?).

Thank you!

ccameron@, would it be possible for sharing latest chromium build to get the exact trace w/ '--show-mac-overlay-borders' flag? I am seeing some close similarity with https://bugs.chromium.org/p/chromium/issues/detail?id=583805 though not 100% sure.

Thank you!
Does the diagnosis in https://bugs.chromium.org/p/chromium/issues/detail?id=749438#c12 fit for this bug too?

You can run Canary with --show-mac-overlay-borders at the command line -- it shouldn't need a Chromium build.
Re c#19. I think yes! Since i've used the same laptop for reproducing both these issues.
