In AcceleratedDrawingAreaProxy::waitForAndDispatchDidUpdateBackingStoreState() we check if the nested compositor is running, which is always true now (if EGL and the required extensions are available). We should check if we are in AC mode instead. 1347845 1 320532 cgarcia 2017-09-12 02:59:07 -0700 Created attachment 320532 Patch 1348809 2 cgarcia 2017-09-14 09:43:42 -0700 Committed r222027: <http://trac.webkit.org/changeset/222027> 320532 2017-09-12 02:59:07 -0700 2017-09-12 07:36:12 -0700 Patch wk2-wl-resize-flickering.diff text/plain 2042 cgarcia ZGlmZiAtLWdpdCBhL1NvdXJjZS9XZWJLaXQvQ2hhbmdlTG9nIGIvU291cmNlL1dlYktpdC9DaGFu Z2VMb2cKaW5kZXggYjhhMjJhN2JhNTcuLjkzNGMyMmJmMTM0IDEwMDY0NAotLS0gYS9Tb3VyY2Uv V2ViS2l0L0NoYW5nZUxvZworKysgYi9Tb3VyY2UvV2ViS2l0L0NoYW5nZUxvZwpAQCAtMSwzICsx LDE4IEBACisyMDE3LTA5LTEyICBDYXJsb3MgR2FyY2lhIENhbXBvcyAgPGNnYXJjaWFAaWdhbGlh LmNvbT4KKworICAgICAgICBbR1RLXVtXYXlsYW5kXSBGbGlja2VyaW5nIHdoZW4gcmVzaXppbmcg dGhlIHdpbmRvdworICAgICAgICBodHRwczovL2J1Z3Mud2Via2l0Lm9yZy9zaG93X2J1Zy5jZ2k/ aWQ9MTc2Nzc0CisKKyAgICAgICAgUmV2aWV3ZWQgYnkgTk9CT0RZIChPT1BTISkuCisKKyAgICAg ICAgVGhpcyByZWdyZXNzZWQgd2hlbiB3ZSBzd2l0Y2hlZCB0byBhbHdheXMgc3RhcnQgdGhlIHdh eWxhbmQgY29tcG9zaXRvci4gSW4KKyAgICAgICAgQWNjZWxlcmF0ZWREcmF3aW5nQXJlYVByb3h5 Ojp3YWl0Rm9yQW5kRGlzcGF0Y2hEaWRVcGRhdGVCYWNraW5nU3RvcmVTdGF0ZSgpIHdlIGNoZWNr IGlmIHRoZSBuZXN0ZWQgY29tcG9zaXRvciBpcworICAgICAgICBydW5uaW5nLCB3aGljaCBpcyBh bHdheXMgdHJ1ZSBub3cgKGlmIEVHTCBhbmQgdGhlIHJlcXVpcmVkIGV4dGVuc2lvbnMgYXJlIGF2 YWlsYWJsZSkuIFdlIHNob3VsZCBjaGVjayBpZiB3ZSBhcmUKKyAgICAgICAgaW4gQUMgbW9kZSBp bnN0ZWFkLgorCisgICAgICAgICogVUlQcm9jZXNzL0FjY2VsZXJhdGVkRHJhd2luZ0FyZWFQcm94 eS5jcHA6CisgICAgICAgIChXZWJLaXQ6OkFjY2VsZXJhdGVkRHJhd2luZ0FyZWFQcm94eTo6d2Fp dEZvckFuZERpc3BhdGNoRGlkVXBkYXRlQmFja2luZ1N0b3JlU3RhdGUpOgorCiAyMDE3LTA5LTEx ICBXZW5zb24gSHNpZWggIDx3ZW5zb25faHNpZWhAYXBwbGUuY29tPgogCiAgICAgICAgIFtpT1Mg V0syXSBTdXBwb3J0IHRhcHBpbmcgdG8gYWRkIGl0ZW1zIHRvIHRoZSBjdXJyZW50IGRyYWcgc2Vz c2lvbiBpbiB3ZWIgY29udGVudApkaWZmIC0tZ2l0IGEvU291cmNlL1dlYktpdC9VSVByb2Nlc3Mv QWNjZWxlcmF0ZWREcmF3aW5nQXJlYVByb3h5LmNwcCBiL1NvdXJjZS9XZWJLaXQvVUlQcm9jZXNz L0FjY2VsZXJhdGVkRHJhd2luZ0FyZWFQcm94eS5jcHAKaW5kZXggYmRhZDJkZDU1YjQuLjZmN2Ux ZTQ2ZTU1IDEwMDY0NAotLS0gYS9Tb3VyY2UvV2ViS2l0L1VJUHJvY2Vzcy9BY2NlbGVyYXRlZERy YXdpbmdBcmVhUHJveHkuY3BwCisrKyBiL1NvdXJjZS9XZWJLaXQvVUlQcm9jZXNzL0FjY2VsZXJh dGVkRHJhd2luZ0FyZWFQcm94eS5jcHAKQEAgLTIxMCwxMSArMjEwLDEwIEBAIHZvaWQgQWNjZWxl cmF0ZWREcmF3aW5nQXJlYVByb3h5Ojp3YWl0Rm9yQW5kRGlzcGF0Y2hEaWRVcGRhdGVCYWNraW5n U3RvcmVTdGF0ZSgpCiAgICAgICAgIHJldHVybjsKICAgICBpZiAoIW1fd2ViUGFnZVByb3h5Lmlz Vmlld1Zpc2libGUoKSkKICAgICAgICAgcmV0dXJuOwotCiAjaWYgUExBVEZPUk0oV0FZTEFORCkg JiYgVVNFKEVHTCkKICAgICAvLyBOZXZlciBibG9jayB0aGUgVUkgcHJvY2VzcyBpbiBXYXlsYW5k IHdoZW4gd2FpdGluZyBmb3IgRGlkVXBkYXRlQmFja2luZ1N0b3JlU3RhdGUgYWZ0ZXIgYSByZXNp emUsCiAgICAgLy8gYmVjYXVzZSB0aGUgbmVzdGVkIGNvbXBvc2l0b3IgbmVlZHMgdG8gaGFuZGxl IHRoZSB3ZWIgcHJvY2VzcyByZXF1ZXN0cyB0aGF0IGhhcHBlbnMgd2hpbGUgcmVzaXppbmcuCi0g ICAgaWYgKFBsYXRmb3JtRGlzcGxheTo6c2hhcmVkRGlzcGxheSgpLnR5cGUoKSA9PSBQbGF0Zm9y bURpc3BsYXk6OlR5cGU6OldheWxhbmQgJiYgV2F5bGFuZENvbXBvc2l0b3I6OnNpbmdsZXRvbigp LmlzUnVubmluZygpKQorICAgIGlmIChQbGF0Zm9ybURpc3BsYXk6OnNoYXJlZERpc3BsYXkoKS50 eXBlKCkgPT0gUGxhdGZvcm1EaXNwbGF5OjpUeXBlOjpXYXlsYW5kICYmIGlzSW5BY2NlbGVyYXRl ZENvbXBvc2l0aW5nTW9kZSgpKQogICAgICAgICByZXR1cm47CiAjZW5kaWYKIAo=
