I have Mint 13 Mate with Totem Movie Player 3.0.1. The buttons (Play/Pause, etc.) all have a "don't-do-it" icon. The buttons do what they are supposed to do when clicked, and the tool-tips do show what each button is, so it's more of a nuisance than a problem. It would be nice, though, if the problem would go away. Would anyone happen to have any idea about what might be going on here? If it matters, my computer has an Intel Ivy Bridge CPU, and is using the built-in graphics engine. The link is to a screenshot of Totem.
