This bug was started after 41 update. It is happen on any computers. If you are unable to reproduce the bug, please run a PC games, such as World Of Warcraft. let it running in the background and try reproduce the bug again. It is NOT a graphic card or driver's problem because it is not happen on any browsers. no matter how much GPU usages, the playback is still smooth. I don't want to disable the hardware acceleration because it will just slow down browsing
