Cursor no longer disappears in full screen mode??

So here's the weird thing. When I go into full screen mode the mouse cursor use to disappear within a few seconds along with the player controls when watching a stream. Then maybe a couple of weeks ago, maybe longer I had to move the cursor slightly before it disappeared after a few seconds. If I didn't it would stay.

Now it just stays no matter what and I have to move the cursor all the way to the right everytime I go full screen mode to hide the cursor. I'm wondering is this an html5 player issue? I tried youtube html5 player and I have to move the cursor abit before it disappears but at least it disappears.

So is there anyway to fix this on Twitch as it gets annoying to have to move the cursor to the right to hide it everytime I want to go full screen. :/
