I've seen https://bugs.webkit.org/show_bug.cgi?id=102957 reproduce, but patching that will get into different other issues. I've been using the controls to make the video full screen. 776465 1 abucur 2012-11-27 01:15:15 -0800 (In reply to comment #0) > Created an attachment (id=176114) [details] > test case > > Adding a video element to a region flow thread and making it fullscreen will throw a bunch of asserts. I've seen https://bugs.webkit.org/show_bug.cgi?id=102957 reproduce, but patching that will get into different other issues. I've been using the controls to make the video full screen. Are you using Chromium? On the Mac port the crash happens before going fullscreen, when moving the cursor over the video element.
