See attached test. 796159 1 abucur 2012-12-20 23:16:20 -0800 To clarify repro: 1. Slowly resize the window so the middle region gets resized as well 2. Even though the resize delta is too small to have text swap regions, the content in the rightmost region bounces vertically with one or two pixels. 900260 2 michelangelo 2013-06-13 11:55:27 -0700 Works for me on today's nightly (r151543) 900518 3 mibalan 2013-06-14 05:37:03 -0700 I'd rather have Andrei take another look at it before deciding it got fixed. He's the one that logged the bug and might have more info on it. 900957 4 mibalan 2013-06-17 01:31:19 -0700 The problem is caused by sub-pixel layout (still reproduces in Canary) and as long as the sub-pixel layout code is still in WebKit (even if it's disabled in the Mac port), the bug should still be open. 1883073 5 bfulgham 2022-07-13 09:25:48 -0700 CSS Regions were removed in Bug 174978.
