Display won't follow sleep settings, uses disabled screensaver instead I've been on the Yosemite and noticed only as of just this morning that my screen was on with a screen saver running.

I have screen savers set to never start, and I have Display sleep set to 10 minutes under Energy Saver.  I went away from my computer again today and came back to find the display on again with the screen saver on again.  I realize I could have processes disrupting display sleep, but why would the screen saver come on if it's been told not to?

Is this some new Yosemite issue?  How might I fix it?
I noticed the same effect in full Yosemite installation: screensaver starts when the computer (macbook air) is put down to sleep. If we add to this the battery "eating" behaviour I observed as well. I have unchecked every item that can use power, icloud and handsoff included, but the system itself needs a lot more energy than Mavericks. The general picture of power management seems to be worse than ever.
