Load the attached file 2. Record events in Timeline Web Inspector tab 3. Observe full screen paints Expected: Transitions complete without repainting the layer defined by the 'container' element with a 3d transform. Actual: Full window is repainted. Notes: I had to use the WebKit Web Inspector Timeline, as the Safari Inspector didn't show repaint dimensions. 888960 1 simon.fraser 2013-05-14 11:44:01 -0700 *** This bug has been marked as a duplicate of bug 50418 *** 201583 2013-05-13 11:05:26 -0700 2013-05-13 11:05:26 -0700 test case opacity_transitions.html text/html 700 dieter PGh0bWw+CjxoZWFkPgogIDxzdHlsZSB0eXBlPSJ0ZXh0L2NzcyI+CiAgICAjbm9kZSB7CiAgICAg IGJhY2tncm91bmQtY29sb3I6IHJlZDsKICAgICAgaGVpZ2h0OiAyMHB4OwogICAgICBvcGFjaXR5 OiAxLjA7CiAgICAgIHdpZHRoOiAyMHB4OwogICAgICAtd2Via2l0LXRyYW5zaXRpb246IG9wYWNp dHkgMC45cyBlYXNlOwogICAgfQoKICAgICNjb250YWluZXIgewogICAgICBoZWlnaHQ6IDEwMCU7 CiAgICAgIHdpZHRoOiAxMDAlOwogICAgICAtd2Via2l0LXRyYW5zZm9ybTogdHJhbnNsYXRlM2Qo MCwwLDApOwogICAgfQogIDwvc3R5bGU+CgogIDxzY3JpcHQgdHlwZT0idGV4dC9qYXZhc2NyaXB0 Ij4KCiAgICB3aW5kb3cub25sb2FkID0gZnVuY3Rpb24oKSB7CiAgICAgIHdpbmRvdy5zZXRJbnRl cnZhbChmdW5jdGlvbigpIHsKICAgICAgICB3aW5kb3cub3BhY2l0eSA9ICF3aW5kb3cub3BhY2l0 eTsKICAgICAgICB2YXIgbm9kZSA9IGRvY3VtZW50LmdldEVsZW1lbnRCeUlkKCdub2RlJyk7CiAg ICAgICAgbm9kZS5zdHlsZS5vcGFjaXR5ID0gd2luZG93Lm9wYWNpdHkgPyAwLjQgOiAxLjA7CiAg ICAgIH0sIDEwMDApOwogICAgfTsKCiAgPC9zY3JpcHQ+CjwvaGVhZD4KCjxib2R5PgogIDxkaXYg aWQ9ImNvbnRhaW5lciI+CiAgICA8ZGl2IGlkPSJub2RlIj4KICAgIDwvZGl2PgogIDwvZGl2PgoK PC9ib2R5Pgo8L2h0bWw+Cg==
