However, sometimes it starts dispatching click events after I click on it a bunch of times. Works as expected in Chrome Canary 35.0.1871.0 and Firefox 27.0.1. Interestingly, the bug repros in Chrome Stable 33.0.1750.146. 989800 1 simon.fraser 2014-03-12 13:03:59 -0700 Does this reproduce in Safari 7? Can you try some other nightlies? Would be useful to know when this regressed. 989880 2 mvujovic 2014-03-12 17:35:24 -0700 (In reply to comment #1) > Does this reproduce in Safari 7? Can you try some other nightlies? Would be useful to know when this regressed. Yes, it repros in Safari 7.0.2 (9537.74.9) on my Mac. I'll try some nightlies when http://nightly.webkit.org comes back up. 990161 3 mvujovic 2014-03-13 14:28:47 -0700 It repros at least as far back as this build: r149492 2013-05-02 21:04:01 GMT http://builds.nightly.webkit.org/files/trunk/mac/WebKit-SVN-r149492.dmg I had to use an older Mac with 10.8.4 to run that build. I don't have a Mac old enough to test father back. 997951 4 dbates 2014-04-05 16:25:01 -0700 This is an regression in the accelerated compositing code exclusively between shipping Safari 5.1.9 (6534.59.8) and Safari Version 6.1 (7537.71) with r90316. The test doesn't reproduce in shipping Safari 5.1.9 (6534.59.8) on Mac OS 10.6.8 (10K549) regardless of the state of accelerated compositing. The test reproduces only with accelerated compositing enabled in Safari Version 6.1 (7537.71) with r90316 on Mac OS X 10.7.5 (11G63). Unfortunately I ran into limitations running nighties on Mac OS 10.6.8 and Mac OS X 10.7.5 that prevented me from further narrowing this range :( 1954369 5 graouts 2023-05-10 10:30:30 -0700 Seems reliable to me with Safari 16: hover works as expected and I always get an alert when clicking. 226340 2014-03-10 15:24:10 -0700 2014-03-10 15:24:10 -0700 Test Case index.html text/html 1001 mvujovic PHN0eWxlPgoKI3RhcmdldCB7CiAgICB3aWR0aDogMTAwcHg7CiAgICBoZWlnaHQ6IDEwMHB4Owog ICAgYmFja2dyb3VuZDogcmVkOwoKICAgIHRyYW5zZm9ybTogdHJhbnNsYXRlWCgwcHgpOwogICAg LXdlYmtpdC10cmFuc2Zvcm06IHRyYW5zbGF0ZVgoMHB4KTsKCiAgICB0cmFuc2l0aW9uOiB0cmFu c2Zvcm0gMTBzIGxpbmVhcjsKICAgIC13ZWJraXQtdHJhbnNpdGlvbjogLXdlYmtpdC10cmFuc2Zv cm0gMTBzIGxpbmVhcjsKfQoKI3RhcmdldDpob3ZlciB7CiAgICBiYWNrZ3JvdW5kOiBncmVlbjsK fQoKPC9zdHlsZT4KPHNjcmlwdD4KCnZhciBoYXNJbml0aWFsVHJhbnNmb3JtID0gdHJ1ZTsKCmZ1 bmN0aW9uIG1vdmVUYXJnZXQoKQp7CiAgICB2YXIgdGFyZ2V0RWwgPSBkb2N1bWVudC5nZXRFbGVt ZW50QnlJZCgidGFyZ2V0Iik7CiAgICB2YXIgbmV3VHJhbnNmb3JtID0gaGFzSW5pdGlhbFRyYW5z Zm9ybSA/ICJ0cmFuc2xhdGVYKDEwMDBweCkiIDogInRyYW5zbGF0ZVgoMHB4KSI7CiAgICB0YXJn ZXRFbC5zdHlsZVsiLXdlYmtpdC10cmFuc2Zvcm0iXSA9IG5ld1RyYW5zZm9ybTsKICAgIHRhcmdl dEVsLnN0eWxlWyJ0cmFuc2Zvcm0iXSA9IG5ld1RyYW5zZm9ybTsKICAgIGhhc0luaXRpYWxUcmFu c2Zvcm0gPSAhaGFzSW5pdGlhbFRyYW5zZm9ybTsKfQoKZnVuY3Rpb24gdGFyZ2V0Q2xpY2tlZCgp CnsKICAgIGFsZXJ0KCJ0YXJnZXQgY2xpY2tlZCEiKTsKfQoKPC9zY3JpcHQ+CjxidXR0b24gb25j bGljaz0ibW92ZVRhcmdldCgpIj5Nb3ZlIGJveDwvYnV0dG9uPgo8YnIvPgo8cD5DbGljayAiTW92 ZSBib3giIGFuZCB0cnkgdG8gY2xpY2sgb24gdGhlIG1vdmluZyBib3guIFdoZW4geW91IGNsaWNr IG9uIHRoZSBib3gsIGl0IHNob3VsZCBkaXNwbGF5IGFuIGFsZXJ0LiBXaGVuIHlvdSBob3ZlciBv dmVyIHRoZSBib3gsIGl0IHNob3VsZCB0dXJuIGdyZWVuLjwvcD4KPGRpdiBpZD0idGFyZ2V0IiBv bmNsaWNrPSJ0YXJnZXRDbGlja2VkKCkiPjwvZGl2Pgo=
