VLC has multiple UI regressions in 16.04

[Alex]

Updated to vlc-2.2.2-4 as part of the 16.04 beta (from 14.04.4), and noticing a number of new issues:

- Menus jump back down to the vlc window from the top of the screen after leaving fullscreen mode
- UI freezes sometimes and won't fullscreen/unfullscreen properly
- Seek takes longer (used to be instantaneous)
- Image corruption when using VA-API that previously wasn't there

Not sure how much of this is due to VLC rather than shared libraries -- I tried downgrading VLC and all of its dependencies to the 15.10 packages, and that didn't help, so it's possible these issues have been around for a little while -- but the packaged version definitely needs a UX pass now.

Please try again with 3.0.0. If the issues still persist, they should probably be filed as separate issues.
