However, on some platforms and in some situations, the window can be layer backed without the WebView necessarily currently being composited. We should check with the window in addition to the WebView before going ahead and using its backing store. <rdar://problem/16679363> 1003104 1 229924 thorton 2014-04-22 16:42:43 -0700 Created attachment 229924 patch 1003107 2 thorton 2014-04-22 16:55:57 -0700 http://trac.webkit.org/changeset/167691 229924 2014-04-22 16:42:43 -0700 2014-04-22 16:53:37 -0700 patch drt-black.diff text/plain 1972 thorton ZGlmZiAtLWdpdCBhL1Rvb2xzL0NoYW5nZUxvZyBiL1Rvb2xzL0NoYW5nZUxvZwppbmRleCA0Mjkz YjMzLi5jOWZlODhjIDEwMDY0NAotLS0gYS9Ub29scy9DaGFuZ2VMb2cKKysrIGIvVG9vbHMvQ2hh bmdlTG9nCkBAIC0xLDUgKzEsMjMgQEAKIDIwMTQtMDQtMjIgIFRpbSBIb3J0b24gIDx0aW1vdGh5 X2hvcnRvbkBhcHBsZS5jb20+CiAKKyAgICAgICAgRHVtcFJlbmRlclRyZWUgZ2VuZXJhdGVzIGJs YWNrIHNuYXBzaG90cyBvbiBzb21lIHBsYXRmb3JtcworICAgICAgICBodHRwczovL2J1Z3Mud2Vi a2l0Lm9yZy9zaG93X2J1Zy5jZ2k/aWQ9MTMyMDI5CisgICAgICAgIDxyZGFyOi8vcHJvYmxlbS8x NjY3OTM2Mz4KKworICAgICAgICBSZXZpZXdlZCBieSBOT0JPRFkgKE9PUFMhKS4KKworICAgICAg ICAqIER1bXBSZW5kZXJUcmVlL21hYy9QaXhlbER1bXBTdXBwb3J0TWFjLm1tOgorICAgICAgICAo Y3JlYXRlQml0bWFwQ29udGV4dEZyb21XZWJWaWV3KToKKyAgICAgICAgRFJUIGNoZWNrcyB3aXRo IHRoZSBXZWJWaWV3IHRvIGRldGVybWluZSB3aGV0aGVyIGl0IGNhbiB1c2UgdGhlIHdpbmRvdydz CisgICAgICAgIGJhY2tpbmcgc3RvcmUgZGlyZWN0bHkgb3IgKGJlY2F1c2Ugb2YgY29tcG9zaXRp bmcpIG5lZWRzIHRvIHRha2UgYSBXaW5kb3dTZXJ2ZXIKKyAgICAgICAgc25hcHNob3QuIEhvd2V2 ZXIsIG9uIHNvbWUgcGxhdGZvcm1zIGFuZCBpbiBzb21lIHNpdHVhdGlvbnMsIHRoZSB3aW5kb3cg Y2FuCisgICAgICAgIGJlIGxheWVyIGJhY2tlZCB3aXRob3V0IHRoZSBXZWJWaWV3IG5lY2Vzc2Fy aWx5IGN1cnJlbnRseSBiZWluZyBjb21wb3NpdGVkLgorICAgICAgICBXZSBzaG91bGQgY2hlY2sg d2l0aCB0aGUgd2luZG93IGluIGFkZGl0aW9uIHRvIHRoZSBXZWJWaWV3IGJlZm9yZSBnb2luZwor ICAgICAgICBhaGVhZCBhbmQgdXNpbmcgaXRzIGJhY2tpbmcgc3RvcmUuCisKKworMjAxNC0wNC0y MiAgVGltIEhvcnRvbiAgPHRpbW90aHlfaG9ydG9uQGFwcGxlLmNvbT4KKwogICAgICAgICBEdW1w UmVuZGVyVHJlZSBnZW5lcmF0ZXMgd2hpdGUgc25hcHNob3RzIG9uIHNvbWUgcGxhdGZvcm1zCiAg ICAgICAgIGh0dHBzOi8vYnVncy53ZWJraXQub3JnL3Nob3dfYnVnLmNnaT9pZD0xMzIwMjYKICAg ICAgICAgPHJkYXI6Ly9wcm9ibGVtLzE2Njc5MzYzPgpkaWZmIC0tZ2l0IGEvVG9vbHMvRHVtcFJl bmRlclRyZWUvbWFjL1BpeGVsRHVtcFN1cHBvcnRNYWMubW0gYi9Ub29scy9EdW1wUmVuZGVyVHJl ZS9tYWMvUGl4ZWxEdW1wU3VwcG9ydE1hYy5tbQppbmRleCAyYWRkYWRhLi44YzZmMjU2IDEwMDY0 NAotLS0gYS9Ub29scy9EdW1wUmVuZGVyVHJlZS9tYWMvUGl4ZWxEdW1wU3VwcG9ydE1hYy5tbQor KysgYi9Ub29scy9EdW1wUmVuZGVyVHJlZS9tYWMvUGl4ZWxEdW1wU3VwcG9ydE1hYy5tbQpAQCAt MTA2LDYgKzEwNiwxMCBAQCBQYXNzUmVmUHRyPEJpdG1hcENvbnRleHQ+IGNyZWF0ZUJpdG1hcENv bnRleHRGcm9tV2ViVmlldyhib29sIG9uc2NyZWVuLCBib29sIGluYwogICAgIGlmIChbdmlldyBf aXNVc2luZ0FjY2VsZXJhdGVkQ29tcG9zaXRpbmddKQogICAgICAgICBvbnNjcmVlbiA9IFlFUzsK IAorICAgIC8vIElmIHRoZSB3aW5kb3cgaXMgbGF5ZXItYmFja2VkLCBpdHMgYmFja2luZyBzdG9y ZSB3aWxsIGJlIGVtcHR5LCBzbyB3ZSBoYXZlIHRvIHVzZSBhIHdpbmRvdyBzZXJ2ZXIgc25hcHNo b3QuCisgICAgaWYgKFt2aWV3LndpbmRvdy5jb250ZW50VmlldyBsYXllcl0pCisgICAgICAgIG9u c2NyZWVuID0gWUVTOworCiAgICAgZmxvYXQgZGV2aWNlU2NhbGVGYWN0b3IgPSBbdmlldyBfYmFj a2luZ1NjYWxlRmFjdG9yXTsKICAgICBOU1NpemUgd2ViVmlld1NpemUgPSBbdmlldyBmcmFtZV0u c2l6ZTsKICAgICBzaXplX3QgcGl4ZWxzV2lkZSA9IHN0YXRpY19jYXN0PHNpemVfdD4od2ViVmll d1NpemUud2lkdGggKiBkZXZpY2VTY2FsZUZhY3Rvcik7Cg==
