It seems that the width is always 800px but the height changes, probably because of scrollbars on the main frame. I'm trying to rewrite the test in bug 183129, that would allow to get rid of these scrollbars.

Does GTK support frame flattening...?

Yes, it does.

[Frédéric Wang (:fredw)]

It seems frameset-flattening-simple is no longer flacky on GTK release but there are other similar tests (e.g. from bug 80129 marked as duplicate) that I did not rewrite and are still flacky. Also I wonder why frameset-flattening-simple is failing on debug build only: https://webkit-test-results.webkit.org/dashboards/flakiness_dashboard.html#showAllRuns=true&showFlaky=true&tests=frameset-flattening
