I'm on a Windows 10 PC and set the screen saver to display photos from a particular folder on both my monitors after being idle for 15 minutes. But after what seems to be a random amount of time, doesn't seem to matter if I had left the PC, shutdown or restarted it will eventually just stop working and reset the timer to 1 minute. I have to manually reapply the timer again and it will work, all the other settings are unchanged.

Could it be it is because I've set DisplayFusion not to start when I launch Windows? So it's basically always off until I need to reset the settings again?

When it stops working and I go check the value, it's changed to 1 minute.
