Half screen youtube?

When I go to youtube and pick out a video I hit the full screen button in the lower left hand corner it only enlarges using only almost half the screen. If I click on that screen it will then enlarge to the full screen. It has never did that before, and after it does fill up the whole screen it will stay that way when I go from video to video. Thanks

What Mac and/or browser are you using??

I only see the "enlarge to full screen" icon at youtube using Safari in Mavericks in the bottom right corner of the video window. And it works as expected.

Yosemite 10.10.5

Safari

It's not a big deal, but when I get use to something and all of a sudden it changes I wonder why.

Not this bad I hope…

Hopefully someone will post some possible solutions for you…

PS: I got a Software Update for Safari today, maybe there's one for you as well and it just maybe might fix your problem. Plus a shutdown + reboot of course. ;D

Oh my, no, not near that bad. My you tube screen is 2/3rd the way down the 27" monitor and about 1/3rd across.

Might be, I don't remember changing anything except for how long the computer stays awake. I may give Applecare a call tonight after work. I will post what they have to say. Thanks pm-r

You are probably mistakenly hitting the "theatre mode" button rather than the "full screen" button:

Or maybe try "YAYS" . Yet Another Youtube Script.

and it's Safari version:

No, I don't think so, I contacted Applecare this morning and we decided to download el capitan to see if that would help which it didn't, but they did see what was happening using Apple Care viewing. I will call them again later this weekend to see what they have to say. They seem to be interested in whats going on, I did ask them if it could be on youtube's end and he said that was possible.

Do you have any kind of third-party extension in your browser?

Sorry, but I am not sure what you are asking me?

Well, let's start at the beginning. You are accessing YouTube through a web browser -- which one?

Safari

So, in Safari's preferences there is a section called "Extensions" -- are there any there?

No, there sure isn't.

Well, at this rate it shouldn't take too long for you to amass another 20,000 posts chas!!!

it's not a fix, however once you go full screen (shows up 1/2 screen size) pause the video, then click play and it will go full screen. I'm having the same issue since the last el capitan update.

I have not been able to find a fix for this yet. Youtube has been notified of the problem. Good luck!

Thanks Gary, for a while there I thought I was the only one this was happening too!

I seems that the problem has been going on for a while so you're not alone. Didn't notice any proper fix…
