The problem seems to be that some tests run so fast that the web process never renders the first frame, so the context is created but never made current. I've checked with apitrace that there are calls to eglQueryContext with null display, causing a EGL_BAD_DISPLAY, but I don't know where those calls are originated, see: 12 eglChooseConfig(dpy = 0x55afaa1eaba0, attrib_list = {EGL_RENDERABLE_TYPE, EGL_OPENGL_ES2_BIT, EGL_RED_SIZE, 8, EGL_GREEN_SIZE, 8, EGL_BLUE_SIZE, 8, EGL_STENCIL_SIZE, 8, EGL_ALPHA_SIZE, 8, EGL_SURFACE_TYPE, EGL_WINDOW_BIT, EGL_NONE}, configs = &0x55afaa1eba50, config_size = 1, num_config = &1) = EGL_TRUE 13 eglCreateContext(dpy = 0x55afaa1eaba0, config = 0x55afaa1eba50, share_context = 0x7f8c24003290, attrib_list = {EGL_CONTEXT_MAJOR_VERSION, 2, EGL_NONE}) = 0x7f8c240391c0 14 eglCreateWindowSurface(dpy = 0x55afaa1eaba0, config = 0x55afaa1eba50, win = 0x7f8c24039130, attrib_list = {}) = 0x7f8c240476a0 15 eglGetCurrentDisplay() = NULL 16 eglGetCurrentContext() = NULL 17 eglGetCurrentDisplay() = NULL 18 eglQueryContext(dpy = NULL, ctx = NULL, attribute = EGL_CONTEXT_CLIENT_TYPE, value = &0) = EGL_FALSE 19 eglGetError() = EGL_BAD_DISPLAY 1373766 1 327358 cgarcia 2017-11-20 05:34:43 -0800 Created attachment 327358 Patch 1373968 2 magomez 2017-11-21 03:36:57 -0800 Looks good to me. The context that is being created is meant to be made current in the compositing thread, so there shouldn't be any problem by making it current when it's created instead of waiting for the first rendered frame. 1373995 3 cgarcia 2017-11-21 05:37:56 -0800 Committed r225078: <https://trac.webkit.org/changeset/225078> 327358 2017-11-20 05:34:43 -0800 2017-11-21 05:17:22 -0800 Patch wpe-context-current.diff text/plain 2094 cgarcia ZGlmZiAtLWdpdCBhL1NvdXJjZS9XZWJLaXQvQ2hhbmdlTG9nIGIvU291cmNlL1dlYktpdC9DaGFu Z2VMb2cKaW5kZXggODhjNzczMTA2ZTQuLmFhYzQyMGRiZmY4IDEwMDY0NAotLS0gYS9Tb3VyY2Uv V2ViS2l0L0NoYW5nZUxvZworKysgYi9Tb3VyY2UvV2ViS2l0L0NoYW5nZUxvZwpAQCAtMSwzICsx LDE5IEBACisyMDE3LTExLTIwICBDYXJsb3MgR2FyY2lhIENhbXBvcyAgPGNnYXJjaWFAaWdhbGlh LmNvbT4KKworICAgICAgICBbV1BFXSBXUEVXZWJQcm9jZXNzOiBDb3VsZG4ndCBmaW5kIGN1cnJl bnQgR0xYIG9yIEVHTCBjb250ZXh0CisgICAgICAgIGh0dHBzOi8vYnVncy53ZWJraXQub3JnL3No b3dfYnVnLmNnaT9pZD0xNzk4ODMKKworICAgICAgICBSZXZpZXdlZCBieSBOT0JPRFkgKE9PUFMh KS4KKworICAgICAgICBJJ20gc2VlaW5nIHRoYXQgbWVzc2FnZSBxdWl0ZSBvZnRlbiB3aGVuIHJ1 bm5pbmcgdGhlIHVuaXQgdGVzdHMuIFRoZSBwcm9ibGVtIHNlZW1zIHRvIGJlIHRoYXQgc29tZSB0 ZXN0cyBydW4gc28KKyAgICAgICAgZmFzdCB0aGF0IHRoZSB3ZWIgcHJvY2VzcyBuZXZlciByZW5k ZXJzIHRoZSBmaXJzdCBmcmFtZSwgc28gdGhlIGNvbnRleHQgaXMgY3JlYXRlZCBidXQgbmV2ZXIg bWFkZSBjdXJyZW50LiBJJ3ZlCisgICAgICAgIGNoZWNrZWQgd2l0aCBhcGl0cmFjZSB0aGF0IHRo ZXJlIGFyZSBjYWxscyB0byBlZ2xRdWVyeUNvbnRleHQgd2l0aCBudWxsIGRpc3BsYXksIGNhdXNp bmcgYSBFR0xfQkFEX0RJU1BMQVksIGJ1dAorICAgICAgICBJIGRvbid0IGtub3cgd2hlcmUgdGhv c2UgY2FsbHMgYXJlIG9yaWdpbmF0ZWQuIE1ha2luZyB0aGUgY29udGV4dCBjdXJyZW50IHJpZ2h0 IGFmdGVyIGl0J3MgY3JlYXRlZCBmaXhlcyB0aGUKKyAgICAgICAgcHJvYmxlbS4KKworICAgICAg ICAqIFNoYXJlZC9Db29yZGluYXRlZEdyYXBoaWNzL3RocmVhZGVkY29tcG9zaXRvci9UaHJlYWRl ZENvbXBvc2l0b3IuY3BwOgorICAgICAgICAoV2ViS2l0OjpUaHJlYWRlZENvbXBvc2l0b3I6OmNy ZWF0ZUdMQ29udGV4dCk6IEFsd2F5cyBjYWxsIG1ha2VDb250ZXh0Q3VycmVudCgpIHJpZ2h0IGFm dGVyIHRoZSBjb250ZXh0IGlzIGNyZWF0ZWQuCisKIDIwMTctMTEtMjAgIENhcmxvcyBHYXJjaWEg Q2FtcG9zICA8Y2dhcmNpYUBpZ2FsaWEuY29tPgogCiAgICAgICAgIFtXUEVdIHdlYmtpdF93ZWJf dmlld19uZXcoKSBzaG91bGQgZW5hYmxlIHNwZWNpZnlpbmcgd3BlX3ZpZXdfYmFja2VuZCBvYmpl Y3QKZGlmZiAtLWdpdCBhL1NvdXJjZS9XZWJLaXQvU2hhcmVkL0Nvb3JkaW5hdGVkR3JhcGhpY3Mv dGhyZWFkZWRjb21wb3NpdG9yL1RocmVhZGVkQ29tcG9zaXRvci5jcHAgYi9Tb3VyY2UvV2ViS2l0 L1NoYXJlZC9Db29yZGluYXRlZEdyYXBoaWNzL3RocmVhZGVkY29tcG9zaXRvci9UaHJlYWRlZENv bXBvc2l0b3IuY3BwCmluZGV4IDNjMDkwZTFjZDJmLi42NGUwNzEwM2Y3OSAxMDA2NDQKLS0tIGEv U291cmNlL1dlYktpdC9TaGFyZWQvQ29vcmRpbmF0ZWRHcmFwaGljcy90aHJlYWRlZGNvbXBvc2l0 b3IvVGhyZWFkZWRDb21wb3NpdG9yLmNwcAorKysgYi9Tb3VyY2UvV2ViS2l0L1NoYXJlZC9Db29y ZGluYXRlZEdyYXBoaWNzL3RocmVhZGVkY29tcG9zaXRvci9UaHJlYWRlZENvbXBvc2l0b3IuY3Bw CkBAIC05MywxMCArOTMsMTEgQEAgdm9pZCBUaHJlYWRlZENvbXBvc2l0b3I6OmNyZWF0ZUdMQ29u dGV4dCgpCiAgICAgaWYgKCFtX2NvbnRleHQpCiAgICAgICAgIHJldHVybjsKIAotICAgIGlmICht X2RvRnJhbWVTeW5jID09IFNob3VsZERvRnJhbWVTeW5jOjpObykgewotICAgICAgICBpZiAobV9j b250ZXh0LT5tYWtlQ29udGV4dEN1cnJlbnQoKSkKLSAgICAgICAgICAgIG1fY29udGV4dC0+c3dh cEludGVydmFsKDApOwotICAgIH0KKyAgICBpZiAoIW1fY29udGV4dC0+bWFrZUNvbnRleHRDdXJy ZW50KCkpCisgICAgICAgIHJldHVybjsKKworICAgIGlmIChtX2RvRnJhbWVTeW5jID09IFNob3Vs ZERvRnJhbWVTeW5jOjpObykKKyAgICAgICAgbV9jb250ZXh0LT5zd2FwSW50ZXJ2YWwoMCk7CiB9 CiAKIHZvaWQgVGhyZWFkZWRDb21wb3NpdG9yOjppbnZhbGlkYXRlKCkK
