We are running CentOS 7.2.1511 (gnome, cinnamon)
Screensaver settings are set globally for all users.
On one of our review stations the screensaver will kick in while RV is in play mode - this is while in presentation mode.
One another machines (same user login) "Application is blocking screensaver" will sometime show and playback will not be interrupted.
Any ideas why RV might not be blocking screensaver in some cases?
Let me know if you need anymore info.
