We have a pref "apz.allow_checkerboarding" which defaults to true, and when set to false, forces APZ to jank rather than checkerboard. This was added back in 2014 (bug 967502), and I don't believe anyone uses it or cares about it any more. However, it requires support in core APZ code, and that supports needs to be maintained. Already, in bug 1465616, we didn't properly maintain it, such that if you set the pref to false, then positioning of fixed elements during times when we would checkerboard can be incorrect. In bug 1459312, I'm making additional changes that would require updates to this code. If this is something no one uses, I'd rather just rip out this code, and avoid having to update it.
