Actual Results: The green polygon looks like it has skew applied to it, instead of rotateX with perspective 3D transform. Expected Results: The green polygon looks like it has rotateX with perspective 3D transform. The top edge should be shorter than the bottom edge and the left and right sides should be slanting inward. The shape (but not the position) should look like rotate-perspective-webkit-bug-no-region.html Workaround: None 871975 1 197151 dalcala 2013-04-09 11:18:08 -0700 Created attachment 197151 expected results (no regions) 895919 2 mibalan 2013-05-31 09:50:44 -0700 After some more investigations it looks like content flowed in a region that has a 3D transform applied does not take into account the perspective (whether specified via -webkit-perspective on a parent or via the perspective() transform function in -webkit-transform). 900220 3 michelangelo 2013-06-13 11:03:54 -0700 Still repros on today's nightly (r151543) 1882807 4 bfulgham 2022-07-12 17:17:17 -0700 CSS Regions were removed in Bug 174978. 197150 2013-04-09 11:17:30 -0700 2013-04-09 11:17:30 -0700 actual results rotateX-perspective-webkit-bug.html text/html 701 dalcala PCFkb2N0eXBlIGh0bWw+CjxodG1sPgo8aGVhZD4KICA8dGl0bGU+M0QgVHJhbnNmb3Jtczogcm90 YXRlWCwgcGVyc3BlY3RpdmUsIHJlZ2lvbiAmIHRyYW5zZm9ybWVkIGNvbnRlbnQgbm9kZTwvdGl0 bGU+CiAgPHN0eWxlPgogICAgI3JlZ2lvbiB7CiAgICAgIHdpZHRoOiAzMDBweDsKICAgICAgaGVp Z2h0OiAzMDBweDsKICAgICAgLXdlYmtpdC1mbG93LWZyb206IGY7CiAgICAgIHBvc2l0aW9uOiBy ZWxhdGl2ZTsKICAgIH0KICAgICNzb3VyY2UgewogICAgICBiYWNrZ3JvdW5kLWNvbG9yOiBncmVl bjsKICAgICAgd2lkdGg6IDIwMHB4OwogICAgICBoZWlnaHQ6IDIwMHB4OwogICAgICBtYXJnaW46 IDAgYXV0byA2MHB4OwogICAgICAtd2Via2l0LWZsb3ctaW50bzogZjsKICAgICAgLXdlYmtpdC10 cmFuc2Zvcm06IHBlcnNwZWN0aXZlKDYwMHB4KSByb3RhdGVYKDQ1ZGVnKTsKICAgIH0KICA8L3N0 eWxlPgo8L2hlYWQ+Cjxib2R5PgogIDxoMz4zRCBUcmFuc2Zvcm1zOiByb3RhdGVYLCBwZXJzcGVj dGl2ZSwgcmVnaW9uICYgdHJhbnNmb3JtZWQgY29udGVudCBub2RlPC9oMz4KICA8cD5CdWc6IFRo ZSBwZXJzcGVjdGl2ZSBpcyBub3QgZ2V0dGluZyBhcHBsaWVkIGNvcnJlY3RseSB3aXRoIHJlZ2lv bnM8L3A+CiAgPGRpdiBpZD0ic291cmNlIj48L2Rpdj4KICA8ZGl2IGlkPSJyZWdpb24iPjwvZGl2 Pgo8L2JvZHk+CjwvaHRtbD4= 197151 2013-04-09 11:18:08 -0700 2013-04-09 11:18:08 -0700 expected results (no regions) rotateX-perspective-webkit-bug-no-region.html text/html 790 dalcala PCFkb2N0eXBlIGh0bWw+CjxodG1sPgo8aGVhZD4KICA8dGl0bGU+M0QgVHJhbnNmb3Jtczogcm90 YXRlWCwgcGVyc3BlY3RpdmUsIG5vIHJlZ2lvbiAmIHRyYW5zZm9ybWVkIGNvbnRlbnQgbm9kZTwv dGl0bGU+CiAgPHN0eWxlPgogICAgI3JlZ2lvbiB7CiAgICAgIHdpZHRoOiAzMDBweDsKICAgICAg aGVpZ2h0OiAzMDBweDsKICAgICAgcG9zaXRpb246IHJlbGF0aXZlOwogICAgfQogICAgI3NvdXJj ZSB7CiAgICAgIGJhY2tncm91bmQtY29sb3I6IGdyZWVuOwogICAgICB3aWR0aDogMjAwcHg7CiAg ICAgIGhlaWdodDogMjAwcHg7CiAgICAgIG1hcmdpbjogMCBhdXRvIDYwcHg7CiAgICAgIC13ZWJr aXQtdHJhbnNmb3JtOiBwZXJzcGVjdGl2ZSg2MDBweCkgcm90YXRlWCg0NWRlZyk7CiAgICB9CiAg PC9zdHlsZT4KPC9oZWFkPgo8Ym9keT4KICA8aDM+M0QgVHJhbnNmb3Jtczogcm90YXRlWCwgcGVy c3BlY3RpdmUsIG5vIHJlZ2lvbiAmIHRyYW5zZm9ybWVkIGNvbnRlbnQgbm9kZTwvaDM+CiAgPHA+ QnVnOiBUaGUgcGVyc3BlY3RpdmUgaXMgbm90IGdldHRpbmcgYXBwbGllZCBjb3JyZWN0bHkgd2l0 aCByZWdpb25zLiBUaGUgcG9zaXRpb24gb2YgdGhlIHBvbHlnb24gaXMgZGlmZmVyZW50IHRoYW4g dGhlIHZlcnNpb24gd2l0aCByZWdpb25zLCBidXQgdGhhdCdzIGFzIGV4cGVjdGVkLiBUaGUgYnVn IGlzIHdpdGggdGhlIHNoYXBlIG9mIHRoZSBwb2x5Z29uLjwvcD4KICA8ZGl2IGlkPSJzb3VyY2Ui PjwvZGl2PgogIDxkaXYgaWQ9InJlZ2lvbiI+PC9kaXY+CjwvYm9keT4KPC9odG1sPg==
