YouTube white screen, black box in the corner

When on YouTube, on Safari, I go into fullscreen, and the screen is usually white, with a black box in the corner, and I have to end up refreshing. I am on a MacBook Pro Retina 2014 model. I have tried uninstalling my flash player, and reinstalling it, but it did nothing. I also tried to do the "run on 32-bit Safari" method, but I don't see the option to. Please help me!

MacBook Pro with Retina display, OS X Yosemite (10.10.5)

1. Safari > Preferences > Privacy > Cookies and website data:


Press the “ Remove All Website Data” button.

Press the “Details” button.

Remove YouTube related cookies.


2. Safari > Preferences > Extensions

Turn all extensions off, relaunch Safari and test.

Turn those on one by one and test.

I am having the same problem. I replaced my laptop 3 times but that issue is still there. I checked in both OS X 10.10.4 and 10.10.5. Don't know how to solve it. Clearing cookies is not working. I have last two days to replace it. Guys please help me if you have solved this issue then.

Also If you click annotation off on Youtube this issue comes again.

It happens to me too. I have Macbook Pro 15" 2014 model. I uninstalled Flash completely, but to no avail. Youtube goes white randomly, and only when the control bar at the bottom of the screen disappears. If I move the mouse to reappear it, the video just plays OK. It's not such a big issue for me, because I do not watch Youtube that much, but is is quite annoying.

Yes, absolutely, I only do not have the black square, it's completely white screen. If I copy the page link, close the tab, open new tab and paste the link there, it does not go white any more. I think it is very incompetent to whipe your entire macbook just because this issue. It's not a hardware issue either. I also think it is not that rare. I hope the thing disappears with El Capitan end of the month.
