A new bug in Apple systems with Nvidia graphics cards can expose private information — but according to Nvidia, it’s not something they can fix. The issue came to light when Evan Andersen launched Diablo III on his Mac. Instead of the game’s familiar splash screen, he saw a perfect screen grab of pornography he’d been, um, reviewing at an earlier point in the day.
According to Evan, the bug occurs because “GPU memory is not erased before giving it to an application. This allows the contents of one application to leak into another. When the Chrome incognito window was closed, it’s [sic] framebuffer was added to the pool of free GPU memory, but it was not erased. When Diablo requested a framebuffer of it’s [sic] own, Nvidia offered up the one previously used by Chrome. Since it wasn’t erased, it still contained the previous contents. Since Diablo doesn’t clear the buffer itself (as it should), the old incognito window was put on the screen again.”
