Yep! :)

As expected, browser_test --mash too.

Test now works with --mus after viz decouple.

This does fail with --enable-viz as expected while in development

Also TabCaptureApiPixelTest.*

On Chrome OS ChromeScreenshotGrabberBrowserTest.TakeScreenshot is failing trying to processes the invalid results of capture

  FATAL:snapshot.cc(25)] Check failed: !image.AsImageSkia().GetRepresentation(1.0f).is_null(). 
  ui::(anonymous namespace)::EncodeImageAsPNG()

I decided to give the TabCapture related tests a go, but with --enable-features=VizDisplayCompositor

A lot of them are now working thanks to all of the work in this space!

Remaining errors I see are:
  -  issue 810389 
  - TabCaptureApiPixelTest.OffscreenTab*
         - Flaky timeouts on CrOS
  - ThumbnailTest.ShouldCaptureOnNavigatingAwaySlowPageLoad 
         - Failure:
       chrome/browser/thumbnails/thumbnail_browsertest.cc:336: Failure
Actual function call count doesn't match EXPECT_CALL(*thumbnail_service(), SetPageThumbnail(Field(&ThumbnailingContext::url, red_url), ImageColorIs(static_cast<SkColor>(0xFFFF0000))))...
         Expected: to be called once
           Actual: never called - unsatisfied and active
  - ThumbnailTest.ShouldCaptureOnNavigatingAwayExplicitWait 
        - times out attempting to acquire a thread lock

I've update  issue 810389  which is better tracking know failures of Tab Capture.

The test listed in this issue has since been fixed. I can no longer reproduce the failure.
