I'm having the same problem. I updated to nVidia's new drivers and it
seems to have worked for now. I would right click and the first option I
would choose would remain on the screen in a semitransparent state until
I played around with the display settings.

I turned off the fade menu item visual effect. I had to turn it back on
as the menus would appear very transparent until I moved my mouse
slightly and then they would appear normally.
