Video issue, Audio issue, both, neither?
Usually while playing video in full screen from website (i.e youtube / drama website) the taskbar will hide themselves after hitting full screen. However this version and the normal chrome version didnt auto hide the taskbar.

i found out that if i hit full screen, thence i click once at the taskbar and click again to the video thence only the taskbar will hide.
