Full Screen Issue when using any browser

Hello,
just wanted to mention that when in the 1.8.3 update ( I reverted to 1.8.0 and it doesn't have this issue ) When I fullscreen a video or when browsing Reddit with playing videos "instant play" or live play whatever the name of the feature is for when you're browsing Reddit for example; I've noticed this issue a lil sooner than 1.8.3 so since 1.0.8 something got fucky.
W10.64bit
-Latest W. Update - 64GB

nvm.. 1.8.0 also has the issue

The codec pack does NOT have ANY effect AT ALL on video playback in your browser. NONE. ZERO.

Your problem is caused by something else.

Hmmmm; Wasn't aware of that. Thank you !

If you are using Adblock plugin, you should replace it with uBlock Origin plugin. That is much better and does not have delay bugs.
