I run a Raspberry Pi 2 OSMC 2016.02-1 using confluence skin. I have the Digital clock screensaver by Vojislav Vlasic installed Sometimes when I try to exit the screensaver by pressing a button to return to the home page it freezes and I have to unplug it and replug to start it again. Just thought I should say something!
Contact the screensaver developer, it’s not likely that this is a OSMC issue.
