I'm seeing the same problem, pictures off screen by about 1/3 to 1/4 screen (cutoff) when using Photos Vista Screensaver.
I have messed with switching primary displays. I have dual display, one 1200 by 800 the other 1920 by 1080.
This looks like bad programming bug on behalf of Microsoft, and they couldn't catch it as of yet.
I have yet to reboot, to see if that improves the situation.
Please comment on
