* Did you change the dimensions of the content area? Even a little? The tsvgx test seems to be sensitive to changes like this. See {{bug|1375479}}, for example. Usually, these sorts of "regressions" aren't real regressions - they just mean that we need to re-baseline our expectations from the test. | * Did you change the dimensions of the content area?

* Additionally, these runs don't have dedicated hardware and have a large variability. At least 30 runs are likely to be needed to get stable statistics (xref [https://bugzilla.mozilla.org/show_bug.cgi?id=1616236 bug 1616236]) | |||
