Hi all, I'm on a 13.3 2014 MBA. Recently it seems that whenever I want to watch a video on youtube from my laptop, the controls (play, rewind/fast forward, full screen, and video quality) aren't seen at all, I can't stop the video, the keyboard controls (spacebar or k to stop the video) are completely ineffective. When the video is finished, suddenly they reappear, but all the same I can't seem to be able to do anything with them. What on earth is going on in your opinion? Btw, I'm using Safari as browser.
