I've been trying to watch videos in fullscreen mode on a secondary display attached to my iMac, it's a Samsung 42" TV, the problem is there's some type of bug which basically duplicates the menu bar, well not literally but it creates a bar where the menu bar should drops down to when the mouse is hovered over the top. It also happens that it'll double glitch and make two bars instead (as if one wasn't annoying enough). Then there's a third bug which brings the controls of VLC to be displayed in the wrong screen.
Here's the screencast of what I'm talking about: http://youtu.be/X2Px53Yh7hA
I'm running Mac OS 10.9.2 (Mavericks)
VLC version 2.1.4
Dual-display, the iMac's native 2560x1440, while the TV only does 1080p
I highly recommend you watch the video before making any suggestions as I reset VLC completely twice.
Once before I started screencasting, to show some proof it does it from a clean install, and then the second time in the video, although I believe I forgot to delete the cache in the video.
