When top, right, bottom & left borders of an element have different colors, at each corner, they cut along the 45 degree angle and bevel next to each other. When using RGBa color values, which is going to be available in CSS3, like-colored edges "overlap" on corners instead of bevel. 101991 1 simon.fraser 2008-12-09 10:19:30 -0800 <rdar://problem/5843531> 107634 2 mrowe 2009-01-29 18:24:45 -0800 *** Bug 23632 has been marked as a duplicate of this bug. *** 183869 3 bugs 2010-01-22 16:33:27 -0800 I suppose the odd behaviour I ran into here: http://m8y.org/tmp/testcase177.xhtml (most noticeable in the enlarged bottom border) is the same? 183874 4 simon.fraser 2010-01-22 16:43:24 -0800 Yep, that looks like the rgba() issue. 184623 5 bugs 2010-01-26 10:16:21 -0800 Simplified testcase: data:text/html,<div style="width:0;border:16px solid rgba(0,0,0,0.3);-webkit-border-radius:5px"></div> 184631 6 bugs 2010-01-26 11:03:44 -0800 Oh, and is this really a minor? I mean, right now the only impact is my borders look a rather ugly in Safari and Chrome, but still, they *do* look ugly. I guess I'm just moderately concerned since it looks like this was filed a year and a half ago. Another year and a half of ugly borders in 10% or so of the browsers out there would be a little unfortunate. And, yes, they look plain in IE, I know. But boss is fine with that, and at least they don't have weird patterns in 'em. 184634 7 simon.fraser 2010-01-26 11:08:24 -0800 *** Bug 31776 has been marked as a duplicate of this bug. *** 184636 8 simon.fraser 2010-01-26 11:09:45 -0800 See also bug 9197, bug 19651. We're aware of this. It's more than minor. 184938 9 47492 darwin 2010-01-26 21:54:38 -0800 Created attachment 47492 Test case that makes the problem more obvious I'll add some notes in here in case someone takes this bug before I find time to do so (won't be for a few months probably). I imagine this bug will be fixed when #9197 and #19651 are resolved but I'll leave it open for now as it makes the other two occur more often and in a more likely case. 357938 10 simon.fraser 2011-02-25 08:36:58 -0800 *** Bug 36103 has been marked as a duplicate of this bug. *** 357940 11 simon.fraser 2011-02-25 08:37:03 -0800 *** Bug 39591 has been marked as a duplicate of this bug. *** 388662 12 simon.fraser 2011-04-19 11:46:30 -0700 http://trac.webkit.org/changeset/84273 400339 13 dbates 2011-05-08 20:47:11 -0700 *** Bug 60363 has been marked as a duplicate of this bug. *** 47492 2010-01-26 21:54:38 -0800 2010-01-26 21:54:38 -0800 Test case that makes the problem more obvious test-case-31776.html text/html 270 darwin PGh0bWw+CjxoZWFkPgogICAgPHN0eWxlIHR5cGU9InRleHQvY3NzIj4KICAgICAgICBkaXYgewog ICAgICAgICAgICAtd2Via2l0LWJvcmRlci1yYWRpdXM6IDUwcHg7CiAgICAgICAgICAgIHdpZHRo OiA1MDBweDsKICAgICAgICAgICAgaGVpZ2h0OiAyMDBweDsKICAgICAgICAgICAgYm9yZGVyOiAx NDBweCBzb2xpZCByZ2JhKDI1NSwwLDAsMC41KTsKICAgICAgICB9CiAgICA8L3N0eWxlPgo8L2hl YWQ+Cjxib2R5PgogICAgPGRpdj48L2Rpdj4KPC9ib2R5Pgo8L2h0bWw+
