when im running a video in fullscreen in vlc on my second monitor or any other video player the top panel bar appears as soon as i give focus to an application on my main monitor. Have never seen this behavior on other desktop environtments. Is it a bug? I can't find any way to fix this.
Bug/missing feature since 2011. Is this ever gonna get looked into? https://bugs.launchpad.net/unity/+bug/853865
