Some of the tests in reftests/writing-mode/ (not currently enabled in automation) do not work reliably across platforms, due to various font and color differences. Some of these may be fixed by using specific, known fonts; in other cases, adding some fuzz annotations may be the best way forward.

Comment on attachment 8553083 [details] [diff] [review] Make some vertical writing-mode reftests more robust, and/or mark as fuzzy where minor subpixel differences occur Review of attachment 8553083 [details] [diff] [review]: ----------------------------------------------------------------- rs=me

Pushed to inbound: https://hg.mozilla.org/integration/mozilla-inbound/rev/4d3bf4fc704e Once bug 1117210 also lands, the current writing-mode reftests are all green with the runtime vertical-text pref enabled.
