Some people turn off double buffering in their video card as it makes
things faster with 3d applications but it can cause issues like this as you
don't have the multiple draws to prevent hovering windows from being
captured.  This is why you will also see tearing when playing back in apps
like Framecycler or Hieroplayer.
