Description Ryosuke Niwa 2013-09-06 22:16:20 PDT

It seems like we've introduced some nondeterministic behavior in WebKit.  Random compositing tests are failing on each run.  This is bad.  It's going to clog EWS and Commit Queue completely.

Committed r155237: <http://trac.webkit.org/changeset/155237>

Did it start with http://trac.webkit.org/changeset/155140 ?

It's hard to tell.  Because there is no single test that has been failing.

It seems like media/video-object-fit.html started failing after that patch on Lion:

EWS seems to indicate something bad happened about 10 hours ago.
Comment 6 Simon Fraser (smfr) 2013-09-06 22:35:31 PDT
That would implicate http://trac.webkit.org/changeset/155196

I've rolled that change out in http://trac.webkit.org/changeset/155235 but that change was in response to EWS getting behind so the underlying issue must be somewhere else.

These two tests are failing for me locally with r155076.
