Comment 19 for bug 1930700

If we're going to do a dot release, we might want to consider deactivating on Linux due to bug 1714282, which I think is actually the most serious issue we've seen. A patch has landed there (which I hope to uplift to 90), but for 89, I'd consider disabling it.

The crash on Windows (bug 1689379) is probably not too big of a concern; it's specifically at shutdown, and it's not really a "bug" that's crashing us, it's a timeout because directwrite is being slow, which we then detect as a hang and deliberately crash. Again, a patch has just landed, which I hope to uplift to 90. I suppose for 89, though, deactivating via the pref would be a better user experience.

I think the other issues were categorized as S2 simply due to being "regressions", but may not be so serious - there are several examples where users have odd font configurations, and have experienced a change because our behavior arguably became *more* correct; I don't think these type of edge cases would justify reverting the feature.

So - yes, I think deactivating in an 89.x dot-release, while we wait for bug 1689379 and bug 1714282 to be fixed in 90, may be a good option here.
