DCHECK hit in ui/aura/window.cc: !visible_ || layer()->GetTargetOpacity() > 0.0f

Project Member Reported by emaxx@chromium.org, Apr 12 2017

Issue description

Chrome Version: ToT
OS: Chrome

What steps will reproduce the problem?
(1) Build a debug build for veyron_minnie and deploy it to a minnie Chromebook.
(2) Install an ARC app, say "Ping" or "Firefox".
(3) Click on the app icon.

What is the expected result?
The app starts.

What happens instead?
Crash:
[FATAL:window.cc(217)] Check failed: !visible_ || layer()->GetTargetOpacity() > 0.0f.


Unfortunately, cannot provide the stack trace as deploying of symbols to a Chromebook seems to be broken for the last few days.


sky@: Scott, assigning to you for triaging. The DCHECK seems to be there for a couple of years, so something outside it has changed to start triggering this now.

I'm not particularly familiar with how arc hooks in to ash. Oshima or Peng likely has a better idea.
