While testing for bug 90097, I came across this bug: According to https://trac.webkit.org/wiki/LayoutUnit paddings are supposed to have subpixel precision, but this sample shows that they are being rounded: http://jsfiddle.net/behdad/ALd5F/5/ Output: span[position:static; padding-right:7.5px]: rect.width=7 span[position:fixed; padding-right:7.5px]: rect.width=7 span[position:absolute; padding-right:7.5px]: rect.width=7 span[position:relative; padding-right:7.5px]: rect.width=7 Applying patches in bug 90097 fixes the two middle cases, but no the other two: span[position:static; padding-right:7.5px]: rect.width=7 span[position:fixed; padding-right:7.5px]: rect.width=7.5 span[position:absolute; padding-right:7.5px]: rect.width=7.5 span[position:relative; padding-right:7.5px]: rect.width=7 1746818 1 rbuis 2021-04-03 14:08:31 -0700 This works these days. 1919862 2 ahmad.saleem792 2022-12-16 02:31:50 -0800 *** Safari Technology Preview 160 *** span[position:static; padding-right:7.5px]: rect.width=7.5 span[position:fixed; padding-right:7.5px]: rect.width=7.5 span[position:absolute; padding-right:7.5px]: rect.width=7.5 span[position:relative; padding-right:7.5px]: rect.width=7.5 *** Chrome Canary 110 *** span[position:static; padding-right:7.5px]: rect.width=7.5 span[position:fixed; padding-right:7.5px]: rect.width=7.5 span[position:absolute; padding-right:7.5px]: rect.width=7.5 span[position:relative; padding-right:7.5px]: rect.width=7.5 *** Firefox Nightly 110 *** span[position:static; padding-right:7.5px]: rect.width=7.5 span[position:fixed; padding-right:7.5px]: rect.width=7.5 span[position:absolute; padding-right:7.5px]: rect.width=7.5 span[position:relative; padding-right:7.5px]: rect.width=7.5 _______ Since all browsers are matching each other, I am going to mark this as "RESOLVED CONFIGURATION CHANGED". Thanks!
