I was not able to reproduce the problem on my ML machine. 758083 3 172226 rniwa 2012-11-04 01:43:03 -0800 Comment on attachment 172226 Patch I'm a bit skeptical but let's try that. 758084 4 172226 rniwa 2012-11-04 01:55:12 -0800 Comment on attachment 172226 Patch Looking at the actual result more closely, this might be a real bug in Chromium. Let's hold off on landing this. http://build.chromium.org/f/chromium/layout_test_results/WebKit_Mac10_8/results/layout-test-results/fast/regions/autoheight-definedheight-changenotdetected-actual.png 758085 5 rniwa 2012-11-04 01:56:28 -0800 Emil & Levi, Is 1px anti-aliasing showing up on the boxes on the left and the bottom right expected? I can't help but think that this is a real bug in Chromium on 10.8. 758521 6 eae 2012-11-05 07:39:54 -0800 (In reply to comment #5) > Emil & Levi, > > Is 1px anti-aliasing showing up on the boxes on the left and the bottom right expected? I can't help but think that this is a real bug in Chromium on 10.8. Depends on what the test is doing, hard to tell from the screenshot. 758539 7 mihnea 2012-11-05 08:04:18 -0800 (In reply to comment #6) > (In reply to comment #5) > > Emil & Levi, > > > > Is 1px anti-aliasing showing up on the boxes on the left and the bottom right expected?

Independent of regions, i have noticed that a simple div using a 50px Ahem font has the same antialiasing, which is gone if one specifies -webkit-font-smoothing: none, hence my proposed fix for the test in Chromium. 172226 2012-11-03 13:55:47 -0700 2012-11-04 01:55:12 -0800 Patch 101101.patch text/plain 1396 mihnea ZGlmZiAtLWdpdCBhL0xheW91dFRlc3RzL0NoYW5nZUxvZyBiL0xheW91dFRlc3RzL0NoYW5nZUxv ZwppbmRleCA1YWVhMzE5Li5lZGI0NWNmIDEwMDY0NAotLS0gYS9MYXlvdXRUZXN0cy9DaGFuZ2VM b2cKKysrIGIvTGF5b3V0VGVzdHMvQ2hhbmdlTG9nCkBAIC0xLDMgKzEsMTQgQEAKKzIwMTItMTEt MDMgIE1paG5lYSBPdmlkZW5pZSAgPG1paG5lYUBhZG9iZS5jb20+CisKKyAgICAgICAgW2Nocm9t aXVtXSBmYXN0L3JlZ2lvbnMvYXV0b2hlaWdodC1kZWZpbmVkaGVpZ2h0LWNoYW5nZW5vdGRldGVj dGVkLmh0bWwgZmFpbHMgb24gTWFjT1MgMTAuOAorICAgICAgICBodHRwczovL2J1Z3Mud2Via2l0 Lm9yZy9zaG93X2J1Zy5jZ2k/aWQ9MTAxMTAxCisKKyAgICAgICAgUmV2aWV3ZWQgYnkgTk9CT0RZ IChPT1BTISkuCisKKyAgICAgICAgVHVybiBvZmYgZm9udC1zbW9vdGhpbmcgZm9yIHRoZSBBaGVt IGZvbnQgdXNlZCBmb3IgY29udGVudCBmbG93ZWQgaW4gcmVnaW9uLgorCisgICAgICAgICogZmFz dC9yZWdpb25zL2F1dG9oZWlnaHQtZGVmaW5lZGhlaWdodC1jaGFuZ2Vub3RkZXRlY3RlZC5odG1s OgorCiAyMDEyLTExLTAyICBTaGlueWEgS2F3YW5ha2EgIDxzaGlueWFrQGNocm9taXVtLm9yZz4K IAogICAgICAgICBbU2hhZG93XSBTaGFkb3dSb290IHNob3VsZCBiZSBhYmxlIHRvIGtub3cgdGhl IGV4aXN0ZW5jZSBvZiA8Y29udGVudD4KZGlmZiAtLWdpdCBhL0xheW91dFRlc3RzL2Zhc3QvcmVn aW9ucy9hdXRvaGVpZ2h0LWRlZmluZWRoZWlnaHQtY2hhbmdlbm90ZGV0ZWN0ZWQuaHRtbCBiL0xh eW91dFRlc3RzL2Zhc3QvcmVnaW9ucy9hdXRvaGVpZ2h0LWRlZmluZWRoZWlnaHQtY2hhbmdlbm90 ZGV0ZWN0ZWQuaHRtbAppbmRleCA5ZTBiMzdkLi5hMTAzYTUwIDEwMDY0NAotLS0gYS9MYXlvdXRU ZXN0cy9mYXN0L3JlZ2lvbnMvYXV0b2hlaWdodC1kZWZpbmVkaGVpZ2h0LWNoYW5nZW5vdGRldGVj dGVkLmh0bWwKKysrIGIvTGF5b3V0VGVzdHMvZmFzdC9yZWdpb25zL2F1dG9oZWlnaHQtZGVmaW5l ZGhlaWdodC1jaGFuZ2Vub3RkZXRlY3RlZC5odG1sCkBAIC0yLDcgKzIsNyBAQAogPGh0bWw+CiAg ICAgPGhlYWQ+CiAgICAgICAgIDxzdHlsZT4KLSAgICAgICAgICAgIC5mbG93Q29udGVudCB7IGZv bnQtc2l6ZTogNTBweDsgY29sb3I6IGdyZWVuOyBmb250LWZhbWlseTogQWhlbTsgfQorICAgICAg ICAgICAgLmZsb3dDb250ZW50IHsgZm9udC1zaXplOiA1MHB4OyBjb2xvcjogZ3JlZW47IGZvbnQt ZmFtaWx5OiBBaGVtOyAtd2Via2l0LWZvbnQtc21vb3RoaW5nOiBub25lOyB9CiAgICAgICAgICAg ICAjYXJ0aWNsZSB7IC13ZWJraXQtZmxvdy1pbnRvOiBmbG93OyB9CiAKICAgICAgICAgICAgIC5y ZWdpb25TaXplIHsgd2lkdGg6IDI1MHB4OyB9Cg==
