Could you please try to remove the screen-saver settings file? The file should be located ~/Library/Preferences/ByHosts/ folder and named something like com.apple.screensaver.xxxx.plist. Set your screen saver preferences once again and see if the issue disappear.

I am also having the same issue.

I'm currently on an nVidia 650M.

Additionally the removal of the screensaver file and resetting of the screen saver through the System Preferences did not fix the issue for me.
