[Alexey Proskuryakov]

New tests landed flaky.

More antialiasing noise! Is this flaky on its own, or caused by a preceding test?

[Truitt Savell]

compositing/iframes/border-uneven-radius-composited-frame.html does reproduce easily on its own with command:

run-webkit-tests --iterations 2000 --exit-after-n-failures 1 --exit-after-n-crashes-or-timeouts 1 --debug-rwt-logging --no-retry --force --no-build -f compositing/iframes/border-uneven-radius-composited-frame.html

but compositing/iframes/border-radius-composited-frame.html does not seem to early reproduce with iterations
