Its weirder than that. The input bug hasn't any obvious effect on the video animation until after you add timed sections to your game loop. Specifically, sleeping the game process after processing the current frame until the beginning of the next frame.
Once I started return CPU cycles back to the system, I got slammed with ghosted events that would continue moving the screen around long after my hands had left the keyboard. I'm also doing Win32 platform code with a similar game loop design in another layer, and that was working fine with identical game code. The entire time, I couldn't believe that was the quality of keyboard input on Linux. Sheesh. https://bugs.gentoo.org/show_bug.cgi?id=610326 --
