    Imagine launching a game on your PC and the black loading screen instead shows the porn you had been viewing hours ago via Google’s incognito browser mode. That’s exactly what happened to Evan Andersen, according to his blog post detailing how an Nvidia GPU driver bug breaks Chrome incognito.

    Andersen said the porn he’d viewed hours previously had been “perfectly preserved” and was “splashed on the screen” while Diablo III was loading. He added:


    So how did this happen? A bug in Nvidia's GPU drivers. 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 framebuffer was added to the pool of free GPU memory, but it was not erased. When Diablo requested a framebuffer of its 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.
