How to get rid of translucency of full screen videos on Mac OS X Mavericks

Mon, 10 Feb 2014 00:13:38 +0000

I recently noticed that whenever I watch a video in full screen on the Mac, the video has a certain level of translucency showing the contents of the window or the desktop behind it. This occurs with all YouTube videos I open in the browser as well as VLC Player, and more and more I find the lack of opacity disturbing.

I haven't tested with every other video player I have yet.

I haven't tested what happens with multiple monitors yet either.

Any suggestions to get rid of this translucency will be greatly appreciated.
