With a simpler test that doesn't use text, it is easier to see that we don't match other browsers. 1829165 1 448653 sam 2022-01-07 18:00:02 -0800 Created attachment 448653 Test using boxes 1829166 2 448654 sam 2022-01-07 18:00:57 -0800 Created attachment 448654 Test using boxes 1829167 3 448655 sam 2022-01-07 18:02:42 -0800 Created attachment 448655 Test using boxes 1829169 4 448656 sam 2022-01-07 18:10:21 -0800 Created attachment 448656 Test using rgb() instead 1829170 5 sam 2022-01-07 18:10:54 -0800 Don't think this is hsla() related. But rather something about how we draw. 1829181 6 sam 2022-01-07 18:39:58 -0800 Looks like this is likely due to using the display colorspace as our working color space for our CGContextRefs. As such, this is not a problem on sRGB displays. We should try to see if we can use extended-srgb as we do on iOS, but it will likely be a bit costly due to the lack of a dedicated scaler. But it is an experiment worth doing. 1831140 7 webkit-bug-importer 2022-01-14 18:00:18 -0800 <rdar://problem/87627670> 448653 2022-01-07 18:00:02 -0800 2022-01-07 18:03:13 -0800 Test using boxes t425-hsla-basic-a.xht application/xhtml+xml 1007 sam PCFET0NUWVBFIGh0bWwgUFVCTElDICItLy9XM0MvL0RURCBYSFRNTCAxLjEvL0VOIiAiaHR0cDov L3d3dy53My5vcmcvVFIveGh0bWwxMS9EVEQveGh0bWwxMS5kdGQiPgo8aHRtbCB4bWxucz0iaHR0 cDovL3d3dy53My5vcmcvMTk5OS94aHRtbCI+Cgk8aGVhZD4KCQk8dGl0bGU+Q1NTIFRlc3Q6IGhz bGEoKTwvdGl0bGU+CgkJPGxpbmsgcmVsPSJhdXRob3IiIHRpdGxlPSJMLiBEYXZpZCBCYXJvbiIg aHJlZj0iaHR0cHM6Ly9kYmFyb24ub3JnLyIgLz4KCQk8bGluayByZWw9ImF1dGhvciIgdGl0bGU9 Ik1vemlsbGEgQ29ycG9yYXRpb24iIGhyZWY9Imh0dHA6Ly9tb3ppbGxhLmNvbS8iIC8+CgkJPGxp bmsgcmVsPSJoZWxwIiBocmVmPSJodHRwOi8vd3d3LnczLm9yZy9UUi9jc3MzLWNvbG9yLyNoc2xh LWNvbG9yIiAvPgoJCTxsaW5rIHJlbD0ibWF0Y2giIGhyZWY9InQ0MjUtaHNsYS1iYXNpYy1hLXJl Zi5odG1sIiAvPgoJCTxtZXRhIG5hbWU9ImZsYWdzIiBjb250ZW50PSIiIC8+CgkJPG1ldGEgbmFt ZT0iYXNzZXJ0IiBjb250ZW50PSJUZXN0IGJhc2ljIGZ1bmN0aW9uaW5nIG9mIGhzbGEoKSBjb2xv cnMuIiAvPgoJCTxzdHlsZSB0eXBlPSJ0ZXh0L2NzcyI+PCFbQ0RBVEFbCgkJaHRtbCwgYm9keSB7 IGJhY2tncm91bmQ6IHdoaXRlOyB9CgkJZGl2IHsgd2lkdGg6IDEyZW07IGhlaWdodDogNmVtOyBt YXJnaW4tdG9wOiAwOyB9CgkJLnJlZiB7IGJhY2tncm91bmQtY29sb3I6IGhzbGEoMTIwLCAxMDAl LCA3MCUsIDEuMCk7IH0KCQkudGVzdCB7IGJhY2tncm91bmQtY29sb3I6IGhzbGEoMTIwLCAxMDAl LCA1MCUsIDAuNik7IH0KCQldXT48L3N0eWxlPgoJPC9oZWFkPgoJPGJvZHk+CgkJPHA+VGVzdCBw YXNzZXMgaWYgeW91IHNlZSBhIHNpbmdsZSBzcXVhcmUsIGFuZCBub3QgdHdvIHJlY3RhbmdsZXMg b2YgZGlmZmVyZW50IGNvbG9ycy48L3A+CgkJPGRpdiBjbGFzcz0icmVmIj48L2Rpdj4KCQk8ZGl2 IGNsYXNzPSJ0ZXN0Ij48L2Rpdj4KCTwvYm9keT4KPC9odG1sPgo= 448654 2022-01-07 18:00:57 -0800 2022-01-07 18:02:42 -0800 Test using boxes t425-hsla-basic-a.html text/html 1007 sam PCFET0NUWVBFIGh0bWwgUFVCTElDICItLy9XM0MvL0RURCBYSFRNTCAxLjEvL0VOIiAiaHR0cDov L3d3dy53My5vcmcvVFIveGh0bWwxMS9EVEQveGh0bWwxMS5kdGQiPgo8aHRtbCB4bWxucz0iaHR0 cDovL3d3dy53My5vcmcvMTk5OS94aHRtbCI+Cgk8aGVhZD4KCQk8dGl0bGU+Q1NTIFRlc3Q6IGhz bGEoKTwvdGl0bGU+CgkJPGxpbmsgcmVsPSJhdXRob3IiIHRpdGxlPSJMLiBEYXZpZCBCYXJvbiIg aHJlZj0iaHR0cHM6Ly9kYmFyb24ub3JnLyIgLz4KCQk8bGluayByZWw9ImF1dGhvciIgdGl0bGU9 Ik1vemlsbGEgQ29ycG9yYXRpb24iIGhyZWY9Imh0dHA6Ly9tb3ppbGxhLmNvbS8iIC8+CgkJPGxp bmsgcmVsPSJoZWxwIiBocmVmPSJodHRwOi8vd3d3LnczLm9yZy9UUi9jc3MzLWNvbG9yLyNoc2xh LWNvbG9yIiAvPgoJCTxsaW5rIHJlbD0ibWF0Y2giIGhyZWY9InQ0MjUtaHNsYS1iYXNpYy1hLXJl Zi5odG1sIiAvPgoJCTxtZXRhIG5hbWU9ImZsYWdzIiBjb250ZW50PSIiIC8+CgkJPG1ldGEgbmFt ZT0iYXNzZXJ0IiBjb250ZW50PSJUZXN0IGJhc2ljIGZ1bmN0aW9uaW5nIG9mIGhzbGEoKSBjb2xv cnMuIiAvPgoJCTxzdHlsZSB0eXBlPSJ0ZXh0L2NzcyI+PCFbQ0RBVEFbCgkJaHRtbCwgYm9keSB7 IGJhY2tncm91bmQ6IHdoaXRlOyB9CgkJZGl2IHsgd2lkdGg6IDEyZW07IGhlaWdodDogNmVtOyBt YXJnaW4tdG9wOiAwOyB9CgkJLnJlZiB7IGJhY2tncm91bmQtY29sb3I6IGhzbGEoMTIwLCAxMDAl LCA3MCUsIDEuMCk7IH0KCQkudGVzdCB7IGJhY2tncm91bmQtY29sb3I6IGhzbGEoMTIwLCAxMDAl LCA1MCUsIDAuNik7IH0KCQldXT48L3N0eWxlPgoJPC9oZWFkPgoJPGJvZHk+CgkJPHA+VGVzdCBw YXNzZXMgaWYgeW91IHNlZSBhIHNpbmdsZSBzcXVhcmUsIGFuZCBub3QgdHdvIHJlY3RhbmdsZXMg b2YgZGlmZmVyZW50IGNvbG9ycy48L3A+CgkJPGRpdiBjbGFzcz0icmVmIj48L2Rpdj4KCQk8ZGl2 IGNsYXNzPSJ0ZXN0Ij48L2Rpdj4KCTwvYm9keT4KPC9odG1sPgo= 448655 2022-01-07 18:02:42 -0800 2022-01-07 18:02:42 -0800 Test using boxes t425-hsla-basic-a.html text/html 400 sam PCFET0NUWVBFIGh0bWw+CjxodG1sPgo8aGVhZD4KPHN0eWxlPgogICAgZGl2IHsgd2lkdGg6IDEy ZW07IGhlaWdodDogNmVtOyBtYXJnaW4tdG9wOiAwOyB9CiAgICAucmVmIHsgYmFja2dyb3VuZC1j b2xvcjogaHNsYSgxMjAsIDEwMCUsIDcwJSwgMS4wKTsgfQogICAgLnRlc3QgeyBiYWNrZ3JvdW5k LWNvbG9yOiBoc2xhKDEyMCwgMTAwJSwgNTAlLCAwLjYpOyB9Cjwvc3R5bGU+CjwvaGVhZD4KPGJv ZHk+CiAgICA8cD5UZXN0IHBhc3NlcyBpZiB5b3Ugc2VlIGEgc2luZ2xlIHNxdWFyZSwgYW5kIG5v dCB0d28gcmVjdGFuZ2xlcyBvZiBkaWZmZXJlbnQgY29sb3JzLjwvcD4KICAgIDxkaXYgY2xhc3M9 InJlZiI+PC9kaXY+CiAgICA8ZGl2IGNsYXNzPSJ0ZXN0Ij48L2Rpdj4KPC9ib2R5Pgo8L2h0bWw+ Cg== 448656 2022-01-07 18:10:21 -0800 2022-01-07 18:10:21 -0800 Test using rgb() instead rgb-alpha-blending.html text/html 458 sam PCFET0NUWVBFIGh0bWw+CjxodG1sPgo8aGVhZD4KPHN0eWxlPgogICAgZGl2IHsgd2lkdGg6IDEy ZW07IGhlaWdodDogNmVtOyBtYXJnaW4tdG9wOiAwOyB9CiAgICAucmVmIHsgYmFja2dyb3VuZC1j b2xvcjogcmdiKDQwJSAxMDAlIDQwJSk7IH0gLyogaHNsYSgxMjAsIDEwMCUsIDcwJSwgMS4wKTsg fSAqLwogICAgLnRlc3QgeyBiYWNrZ3JvdW5kLWNvbG9yOiByZ2IoMCUgMTAwJSAwJSAvIDAuNik7 IH0gLyogaHNsYSgxMjAsIDEwMCUsIDUwJSwgMC42KTsgfSAqLwo8L3N0eWxlPgo8L2hlYWQ+Cjxi b2R5PgogICAgPHA+VGVzdCBwYXNzZXMgaWYgeW91IHNlZSBhIHNpbmdsZSBzcXVhcmUsIGFuZCBu b3QgdHdvIHJlY3RhbmdsZXMgb2YgZGlmZmVyZW50IGNvbG9ycy48L3A+CiAgICA8ZGl2IGNsYXNz PSJyZWYiPjwvZGl2PgogICAgPGRpdiBjbGFzcz0idGVzdCI+PC9kaXY+CjwvYm9keT4KPC9odG1s Pgo=
