Google Search is broken (creates non-darkened rectangles on some results), creates squares in search suggestions buttons at the end of the page

Works as described, yet I am wondering why are there two gleaming white buttons for "Google Search" and "I'm Feeling Lucky" smack in the page. Seems to defeat the entire purpose of having a dark theme. I would prefer to have these elements also dark, with light lettering yet cannot seem to find a theme which gives this option. Will continue to look for one. *sigh*
