This looks like a graphic bug. You could try to change the theme and see if it persist or is it specific to the default Unity theme. Also, provide some info about your graphic card and drivers so people can help. – darent Feb 20 '14 at 1:32

My graphics card is AMD Radeon HD 6310. I am not using proprietarian drivers because the installation always fails. – user189199 Feb 20 '14 at 7:29
