menu scroll transparency

It's hard to capture this (see screenshot for general idea), but basically they render the stuff underneath, but in a glitchier way. They're not outstanding glitches but you can see somethings not right.

So:

1. open a long menu that requires scrolls
2. the menu scrolls will be transparent, rendering the stuff that would be underneath if the scroll wasn't there
3. when you hover over them, they will colour up grey, but _underneath_ the text, so you can still see it
4. the text doesn't update while you scroll
5. when you move your mouse elsewhere, it looks like step 2 again

Also, not sure if this is on purpose or not, but the grey hover effect leaves a white border on the top or bottom edge, depending where the button is.
