I upgraded to OpenElec 6.0.1 using the Generic x86_64 from OpenElec but I've noticed lately that the box is not responsive sometimes during playback and you can't press pause/stop like I used to or the on screen menus don't go away and the counting timer showing progress is displaying.

I put the tar file in /storage/.update folder and rebooted as per the procedures

Do I need to reimage my Chromebox and what is the best procedure?

Is this a common problem with the Chromebox or OpenElec?

I was having problems with some of my plugins so I just upgraded OpenElec first and ran into these problems.

I've had such issues myself with Kodi 15. You could try setting vsync to "Let driver decide". It fixed it for me.
