When flowing such an element inside a named flow the composited layer isn't preserved/created anymore. In the attached file, toggle between `flow-into: flow` and `flow-into: none` for the gray div with text - when flow-into is specified, a composited layer is no longer created (this can be inspected via the Debug > Drawing/Compositing flags > Show compositing borders or Debug > Show RenderLayer tree menu entries in Safari/WK nightly) 894023 1 202983 mibalan 2013-05-27 07:47:45 -0700 Created attachment 202983 Test-case 896225 2 203525 mibalan 2013-06-02 08:49:07 -0700 Created attachment 203525 Test-case 900207 3 michelangelo 2013-06-13 10:50:53 -0700 Still repros on today's nightly (r151543) 976323 4 mihnea 2014-02-04 06:53:03 -0800 Fixed in WebKit nighly which was expected after we enabled ACC for elements displayed in regions. 202983 2013-05-27 07:47:45 -0700 2013-06-02 08:49:07 -0700 Test-case 3d-transform-001.html text/html 438 mibalan PCFkb2N0eXBlIGh0bWw+CjxodG1sIGxhbmc9ImVuIj4KPGhlYWQ+Cgk8bWV0YSBjaGFyc2V0PSJV VEYtOCI+Cgk8dGl0bGU+QWNjZWxlcmF0ZWQgY29tcG9zaXRpbmcgZHVlIHRvIDNEIHRyYW5zZm9y bXM8L3RpdGxlPgoJPGxpbmsgcmVsPSJzdHlsZXNoZWV0IiBocmVmPSJjb21tb24uY3NzIj4KCTxz dHlsZT4KCS5ib3ggewoJCXdpZHRoOiAxMDBweDsKCQloZWlnaHQ6IDEwMHB4OwoJCS13ZWJraXQt dHJhbnNmb3JtOiByb3RhdGVYKDIwZGVnKSByb3RhdGVZKDQ1ZGVnKSByb3RhdGVaKDIwZGVnKTsK CX0KCTwvc3R5bGU+CjwvaGVhZD4KPGJvZHk+Cgk8ZGl2IGNsYXNzPSJib3ggbW9ub3NwYWNlIGZs b3ciPm9uZSB0d28gdGhyZWUgZm91ciBmaXZlIHNpeCBzZXZlbjwvZGl2PgoJPGRpdiBjbGFzcz0i cmVnaW9uIGJvcmRlcmVkIj48L2Rpdj4KPC9ib2R5Pgo8L2h0bWw+ 203525 2013-06-02 08:49:07 -0700 2013-06-02 08:49:07 -0700 Test-case 116827_repro.zip application/zip 1084 mibalan UEsDBBQACAAIAEGYtEIAAAAAAAAAAAAAAAAVABAAM2QtdHJhbnNmb3JtLTAwMS5odG1sVVgMAOto q1H6SJpR9QEUAF1Ry07DMBA8t1+x+FQObcpLQsWJhIT4ApCAm2NvYquON7K3TSvEv+O0Eao42TO7 OzNryytDmo89guXOV3M5HuBVaEuBQYwEKlPNZ7JDVqCtigm5FO9vr8tHMfLs2GP1rDV6jIrRgKau p+TYhRbMDoEJ7l6AowqpodglWZxn8rB3YQsRfSkSHz0mi8gCbMSmFFmmo7DSKZ18Tg35sqrpAN/z 2Wxwhu0Gbtbr/vCUsUXXWr4glgPWW8fLP+cNROIc8WNxuzbYXk/wc3H/cAG/pmqW+Mm+xWQsi/NL yJrMcQxk3B60VymVYoyUs1LqlUZoPA2iopA3Hwg4b5M52kVo3B4huQMk3GOQRVb4JxSxdRSgpmgw ohHV1CSLs2sOMX7TL1BLBwgBV/RVIAEAALYBAABQSwMEFAAIAAgAKVi3QgAAAAAAAAAAAAAAAAoA EABjb21tb24uY3NzVVgMAO1oq1HOzJ1R9QEUAKWT0XKjIBSGr+NTcNnOFMeY2m7MTfcxenmMgEwU LOIk2U7ffQ+gySaxadq9Q/jOf+ADY6hYQ96jGdfKUg6NrPc5+Y2Tq2Guk39YTtKk3eFMLRWjFZOi sjmZO+gjiuJGK921sGYXQYeVb6QVeudyClhvhNG9Kula19rkpHagMLAPXPfWg/Ett7K0FSYkIfaQ GL4920Bd04uK7LQgO/LWgBLssuK8x1M6lhRSTOBnHebHFoU2JTOs9Gf1Y/TS7kgJXYWzuBI4Xmuw XqwboAXGLSY2YIRUOUnidBD3Qres2EhLN2zPDTSsI21fd+FSjPa3PNN4GdLuXd1yucScj2hm9flS mvkV195HUKm4VNL6rLENKNmAlVpRhc3y0Gw1tV72xg9cdNZNI9KwdWCgtswosGxFpkjcRUjDZ9Er FDLu7TMJRluwpxZGyN1yx7Vp8oF6vUvuT6RcIRdPScnE/cFUmL9JVUC/cJVOm7KykUpQ3qvBl/uL wEyy33bVtVLdZmpR3uE7WTyQeZw+4L3+wuHjUciX/rB+7uqeMxeBxenjqU63lZtkOvBnKq/o+U/x k895/J23/57GfeMxrc4Jd0RsmMC6C8TdyIBEMShtK2bolTDhw0bwaqhD/wJQSwcI7y9bpdgBAAAI BgAAUEsBAhUDFAAIAAgAQZi0QgFX9FUgAQAAtgEAABUADAAAAAAAAAAAQKSBAAAAADNkLXRyYW5z Zm9ybS0wMDEuaHRtbFVYCADraKtR+kiaUVBLAQIVAxQACAAIAClYt0LvL1ul2AEAAAgGAAAKAAwA AAAAAAAAAECkgXMBAABjb21tb24uY3NzVVgIAO1oq1HOzJ1RUEsFBgAAAAACAAIAkwAAAJMDAAAA AA==
