The bug is that we treat the RenderSVGRoot as a layout boundary, but when it has overflow, we need to propagate layout to the containers, so that the inline boxes compute the correct overflow. 1492675 1 webkit-bug-importer 2019-01-08 11:40:45 -0800 <rdar://problem/47122527> 1896046 2 ahmad.saleem792 2022-09-03 11:10:32 -0700 I am able to reproduce this bug in Safari 15.6.1 and Safari Technology Preview 152 using attached test css and when the green tile goes to bottom right corner, it clips and does not show full box immediately and sometime it shows and sometime clipped. All other browsers (Chrome Canary 107 and Firefox Nightly 106) work fine. Thanks! 1948929 3 ahmad.saleem792 2023-04-14 21:34:55 -0700 When I merge Blink's patch as part of bug 199364, this also get fixed. Tested locally. Last time, I did the PR here - https://github.com/WebKit/WebKit/pull/9138 We can't merge Blink's patch (test cases) since they can be flaky. 1999219 4 ahmad.saleem792 2023-12-13 01:16:03 -0800 @Karl - is it reproducible for you. It isn't reproducible to me anymore. 1999230 5 karlcow 2023-12-13 03:26:38 -0800 Ahmad, Simon, I have two different behaviors: Scenario A 1. Load the test case 2. stay on the window Result: The green box after moving is not clipped Scenario B 1. Load the test case 2. Go to the Finder Result: The green box after moving is clipped 1999231 6 karlcow 2023-12-13 03:27:36 -0800 but if in Scenario B if I click on the window the box gets unclipped again. 1999232 7 karlcow 2023-12-13 03:29:01 -0800 Firefox and Chrome never clips the green box. 1999365 8 simon.fraser 2023-12-13 12:42:24 -0800 You need to put the Safari window into the background to see the bug. It still reproduces. 1999425 9 simon.fraser 2023-12-13 15:23:44 -0800 Turn on layer borders in web inspector to see the tiling change in background windows. 266901 2015-12-08 09:53:33 -0800 2015-12-08 09:53:33 -0800 Testcase svg-broken-by-tiling.html text/html 547 simon.fraser PCFET0NUWVBFIEhUTUw+CjxoZWFkPgogICAgPHN0eWxlPgogICAgICAgIGJvZHkgewogICAgICAg ICAgICBtYXJnaW46IDA7CiAgICAgICAgfQogICAgICAgIAogICAgICAgIHN2ZyB7CiAgICAgICAg ICAgIGJvcmRlcjogMXB4IHNvbGlkIGJsYWNrOwogICAgICAgIH0KICAgIDwvc3R5bGU+CjwvaGVh ZD4KPHN2ZyBpZD0ic3Zncm9vdCIgd2lkdGg9IjUwMCIgaGVpZ2h0PSI1MDAiIG92ZXJmbG93PSJ2 aXNpYmxlIj4KICA8c3ZnIGlkPSJjYW52YXNCYWNrZ3JvdW5kIiB4PSIwIiB5PSIwIiB3aWR0aD0i NTAwIiBoZWlnaHQ9IjUwMCI+CiAgICA8cmVjdCB3aWR0aD0iMjAwIiBoZWlnaHQ9IjIwMCIgZmls bD0iZ3JlZW4iIHN0cm9rZS13aWR0aD0iNSIgc3Ryb2tlPSJibHVlIi8+CiAgPC9zdmc+Cjwvc3Zn Pgo8c2NyaXB0PgogIHNldFRpbWVvdXQoZnVuY3Rpb24oKSB7CiAgICBjYW52YXNCYWNrZ3JvdW5k LnNldEF0dHJpYnV0ZSgneCcsIDQwMCk7CiAgICBjYW52YXNCYWNrZ3JvdW5kLnNldEF0dHJpYnV0 ZSgneScsIDQwMCk7CiAgfSwgMzAwMCk7Cjwvc2NyaXB0Pg==
