Traces of selector are left behind above windows in Alt+Tab

Project Member Reported by varkha@chromium.org, Sep 8 2016

Issue description

Version: 54.0.2840.13 (Dev)
OS: Chrome OS

What steps will reproduce the problem?
(1) Have more than 2 windows on screen
(2) Alt+Tab
(3) Shift+Alt+Tab to return to the first window

What is the expected output?
First window selected, no trace of selector on the second window

What do you see instead?
First window selected but traces of the selector widget remain after animation (look closely at the Downloads caption in attached screenshot).

Please use labels and text to provide additional information.
Looks like individual animation frames leave some pattern behind. I am not seeing this in simulation build, only on device. Also no seeing this when the window tiles move behind the selector as part of Alt+Tab sequence.

At the end of Alt+Tab I see this: Note that it is full height of the dark shield.

I no longer see this in 54.0.2840.33. Could https://codereview.chromium.org/2333323003/ (merged in M-54) have fixed this?

that would not surprise me.

Comment 4 by varkha@chromium.org, Sep 28 2016

Would it be possible to confirm, so that if we ever revert that change (if and when the blur is optimized), we won't introduce a regression?

How would we confirm that? Merge the blur back in and see if the problem comes back? :)

If you're asking for a regression test, I have no idea how we'd write a test for this anyway.

+mdm was seeing this issue. Mike, is it resolved for you now (on 54.0.2840.33 or newer)?

I was thinking local revert, build, deploy and try that local build on a device if you have access to a Chrome OS device. This may not be the easiest though.

I could reproduce this with 54.0.2840.24, but no longer on 54.0.2840.43.
