Bug 197507 – [GTK] Lots of flaky tests happening after r244182 "requestAnimationFrame should execute before the next frame"

• Status: RESOLVED
• Resolution: FIXED
• Component: WebKitGTK

fast/css/transition-color-unspecified.html [ Timeout Pass ]

This is pretty suspicious, as it always times out on the first run since r244182, but there's no info about why.

Said, do you have any clue about how can r244182 be affecting this?

[Miguel Gomez]

This test made me suspicious of r244182 as the reason of many tests that started timing out on the first run. I've rechecked and I found several other tests started failing on that revision or close ones. Also, these tests have in common that they don't have any output: no diff, no stderr, nothing, just a timeout.

This could also be related to the flaky tests I reported on https://bugs.webkit.org/show_bug.cgi?id=197497 and  https://bugs.webkit.org/show_bug.cgi?id=197498. On a second look I found that they started failing after r244182 as well. At least there are some diffs in those tests that can shed some light to the issue, but the summary is that they are timing out as well.

Said, do you see any pattern here? Any clues about where to look for the problem?
