199826 2019-07-16 07:23:11 -0700 [GTK] No web view updates after swapping web process if AC mode is forced 2019-07-17 01:21:22 -0700 1 1 1 Unclassified WebKit WebKitGTK WebKit Nightly Build Unspecified Unspecified RESOLVED FIXED https://bugs.webkit.org/show_bug.cgi?id=199570 Gtk P2 Normal --- 1 cgarcia webkit-unassigned bugs-noreply mcatanzaro oldest_to_newest 1553169 0 cgarcia 2019-07-16 07:23:11 -0700 This can be easily reproduced with MiniBrowser. 1- Start MB with WEBKIT_FORCE_COMPOSITING_MODE=1 2- Wait until webkitgtk.org loads 3- Load google.com (or any other page that make a cross site navigation) This is because when AC mode is forced the provisional page creates a drawing area that is always in AC mode. When swapping processes, the current drawing area is destroyed (which exists AC mode) and the provisional one is set. From that point the web process is in AC mode but the UI process isn't. We need to update the compositing mode when swapping processes. 1553170 1 374206 cgarcia 2019-07-16 07:26:58 -0700 Created attachment 374206 Patch 1553460 2 cgarcia 2019-07-17 01:21:22 -0700 Committed r247506: <https://trac.webkit.org/changeset/247506> 374206 2019-07-16 07:26:58 -0700 2019-07-16 07:56:05 -0700 Patch wk2-ac-forced.diff text/plain 2632 cgarcia ZGlmZiAtLWdpdCBhL1NvdXJjZS9XZWJLaXQvQ2hhbmdlTG9nIGIvU291cmNlL1dlYktpdC9DaGFu Z2VMb2cKaW5kZXggNzM4MTUwMDBlOTIuLjMxMjEyMDU5NTc4IDEwMDY0NAotLS0gYS9Tb3VyY2Uv V2ViS2l0L0NoYW5nZUxvZworKysgYi9Tb3VyY2UvV2ViS2l0L0NoYW5nZUxvZwpAQCAtMSwzICsx LDE5IEBACisyMDE5LTA3LTE2ICBDYXJsb3MgR2FyY2lhIENhbXBvcyAgPGNnYXJjaWFAaWdhbGlh LmNvbT4KKworICAgICAgICBbR1RLXSBObyB3ZWIgdmlldyB1cGRhdGVzIGFmdGVyIHN3YXBwaW5n IHdlYiBwcm9jZXNzIGlmIEFDIG1vZGUgaXMgZm9yY2VkCisgICAgICAgIGh0dHBzOi8vYnVncy53 ZWJraXQub3JnL3Nob3dfYnVnLmNnaT9pZD0xOTk4MjYKKworICAgICAgICBSZXZpZXdlZCBieSBO T0JPRFkgKE9PUFMhKS4KKworICAgICAgICBUaGlzIGlzIGJlY2F1c2Ugd2hlbiBBQyBtb2RlIGlz IGZvcmNlZCB0aGUgcHJvdmlzaW9uYWwgcGFnZSBjcmVhdGVzIGEgZHJhd2luZyBhcmVhIHRoYXQg aXMgYWx3YXlzIGluIEFDCisgICAgICAgIG1vZGUuIFdoZW4gc3dhcHBpbmcgcHJvY2Vzc2VzLCB0 aGUgY3VycmVudCBkcmF3aW5nIGFyZWEgaXMgZGVzdHJveWVkICh3aGljaCBleGlzdHMgQUMgbW9k ZSkgYW5kIHRoZSBwcm92aXNpb25hbAorICAgICAgICBvbmUgaXMgc2V0LiBGcm9tIHRoYXQgcG9p bnQgdGhlIHdlYiBwcm9jZXNzIGlzIGluIEFDIG1vZGUgYnV0IHRoZSBVSSBwcm9jZXNzIGlzbid0 LiBXZSBuZWVkIHRvIHVwZGF0ZSB0aGUKKyAgICAgICAgY29tcG9zaXRpbmcgbW9kZSB3aGVuIHN3 YXBwaW5nIHByb2Nlc3Nlcy4KKworICAgICAgICAqIFVJUHJvY2Vzcy9BUEkvZ3RrL1dlYktpdFdl YlZpZXdCYXNlLmNwcDoKKyAgICAgICAgKHdlYmtpdFdlYlZpZXdCYXNlRGlkRXhpdFdlYlByb2Nl c3MpOgorICAgICAgICAqIFVJUHJvY2Vzcy9Db29yZGluYXRlZEdyYXBoaWNzL0RyYXdpbmdBcmVh UHJveHlDb29yZGluYXRlZEdyYXBoaWNzLmg6CisKIDIwMTktMDctMTYgIENhcmxvcyBHYXJjaWEg Q2FtcG9zICA8Y2dhcmNpYUBpZ2FsaWEuY29tPgogCiAgICAgICAgIFtXUEVdW0dUS10gVUkgcHJv Y2VzcyBjcmFzaCBkdWUgdG8gTlVMTCBkZXJlZmVyZW5jZSBpbiB3ZWJraXRXZWJWaWV3UmVzb3Vy Y2VMb2FkU3RhcnRlZCgpCmRpZmYgLS1naXQgYS9Tb3VyY2UvV2ViS2l0L1VJUHJvY2Vzcy9BUEkv Z3RrL1dlYktpdFdlYlZpZXdCYXNlLmNwcCBiL1NvdXJjZS9XZWJLaXQvVUlQcm9jZXNzL0FQSS9n dGsvV2ViS2l0V2ViVmlld0Jhc2UuY3BwCmluZGV4IDRhMzNhNTY0ODcxLi5hYTE4YmQxNjFiYiAx MDA2NDQKLS0tIGEvU291cmNlL1dlYktpdC9VSVByb2Nlc3MvQVBJL2d0ay9XZWJLaXRXZWJWaWV3 QmFzZS5jcHAKKysrIGIvU291cmNlL1dlYktpdC9VSVByb2Nlc3MvQVBJL2d0ay9XZWJLaXRXZWJW aWV3QmFzZS5jcHAKQEAgLTE3MDAsNiArMTcwMCw4IEBAIHZvaWQgd2Via2l0V2ViVmlld0Jhc2VE aWRSZWxhdW5jaFdlYlByb2Nlc3MoV2ViS2l0V2ViVmlld0Jhc2UqIHdlYmtpdFdlYlZpZXdCYXNl CiAgICAgZ3RrX3dpZGdldF9xdWV1ZV9yZXNpemVfbm9fcmVkcmF3KEdUS19XSURHRVQod2Via2l0 V2ViVmlld0Jhc2UpKTsKIAogICAgIFdlYktpdFdlYlZpZXdCYXNlUHJpdmF0ZSogcHJpdiA9IHdl YmtpdFdlYlZpZXdCYXNlLT5wcml2OworICAgIGF1dG8qIGRyYXdpbmdBcmVhID0gc3RhdGljX2Nh c3Q8RHJhd2luZ0FyZWFQcm94eUNvb3JkaW5hdGVkR3JhcGhpY3MqPihwcml2LT5wYWdlUHJveHkt PmRyYXdpbmdBcmVhKCkpOworICAgIHdlYmtpdFdlYlZpZXdCYXNlVXBkYXRlQWNjZWxlcmF0ZWRD b21wb3NpdGluZ01vZGUod2Via2l0V2ViVmlld0Jhc2UsIGRyYXdpbmdBcmVhLT5sYXllclRyZWVD b250ZXh0KCkpOwogCiAgICAgaWYgKHByaXYtPnZpZXdHZXN0dXJlQ29udHJvbGxlcikKICAgICAg ICAgcHJpdi0+dmlld0dlc3R1cmVDb250cm9sbGVyLT5jb25uZWN0VG9Qcm9jZXNzKCk7CmRpZmYg LS1naXQgYS9Tb3VyY2UvV2ViS2l0L1VJUHJvY2Vzcy9Db29yZGluYXRlZEdyYXBoaWNzL0RyYXdp bmdBcmVhUHJveHlDb29yZGluYXRlZEdyYXBoaWNzLmggYi9Tb3VyY2UvV2ViS2l0L1VJUHJvY2Vz cy9Db29yZGluYXRlZEdyYXBoaWNzL0RyYXdpbmdBcmVhUHJveHlDb29yZGluYXRlZEdyYXBoaWNz LmgKaW5kZXggZGZkZDc3ZjhlM2IuLmQ3Njk1MDg4ZTdjIDEwMDY0NAotLS0gYS9Tb3VyY2UvV2Vi S2l0L1VJUHJvY2Vzcy9Db29yZGluYXRlZEdyYXBoaWNzL0RyYXdpbmdBcmVhUHJveHlDb29yZGlu YXRlZEdyYXBoaWNzLmgKKysrIGIvU291cmNlL1dlYktpdC9VSVByb2Nlc3MvQ29vcmRpbmF0ZWRH cmFwaGljcy9EcmF3aW5nQXJlYVByb3h5Q29vcmRpbmF0ZWRHcmFwaGljcy5oCkBAIC00OCw2ICs0 OCw3IEBAIHB1YmxpYzoKICNlbmRpZgogCiAgICAgYm9vbCBpc0luQWNjZWxlcmF0ZWRDb21wb3Np dGluZ01vZGUoKSBjb25zdCB7IHJldHVybiAhbV9sYXllclRyZWVDb250ZXh0LmlzRW1wdHkoKTsg fQorICAgIGNvbnN0IExheWVyVHJlZUNvbnRleHQmIGxheWVyVHJlZUNvbnRleHQoKSBjb25zdCB7 IHJldHVybiBtX2xheWVyVHJlZUNvbnRleHQ7IH0KIAogcHJpdmF0ZToKICAgICAvLyBEcmF3aW5n QXJlYVByb3h5Cg==
