I've been working in FCPX since it came out, and was a FCP7 editor before that. Every so often I'll see in one of my exports in FCPX a visual piece of something, be it a graphic, or text, that isn't really there (no where to be found in my timeline), but it's showing up on export. What the heck is that?? Is it a video card issue maybe? Or a FCPX glitch??
