That's an issue with qtbase-opensource-src, the xenial update has

"  * Remove disable_overlay_scrollbars.diff as overlay scrollbars were
dropped."

That's still needed though, they were not removed from gtk2 and the
issue ... Timo, can you fix that in the next upload?

  If the overlay-scrollbar packages are removed menu windows open, vlc complains about module not able to be loaded & menus are not as accessible as they should be. 
  If vlc is opened with export LIBOVERLAY_SCROLLBAR=0 && vlc then all is well. 
  As I understand overlay-scrollbars is not going to be used or something like that, hence yet again starting bug on vlc though other packages like calibre may be affected & or the cause
