Here is my problem and I have never seen this before in Blender:

I'm making a Minecraft Animation and on multiple frames there are unrendered transparent pixels scattered across the image (resulting in black spots). I have googled around and only found answers related to Cycles render which doesn't apply to my situation as I use Blender Internal.

I made a video explanation to show in detail what is happening:

UPDATE: Thank's all those who helped me out. It turned out to be a problem with "Auto Ray Bias." This thread answered my problem. Cause of Alpha or Black Artefacts in Render

    Check whether this isn't z-fighting, make sure to unhide all the objects in scene and see if there are any surprises, also check whether there's repeating geometry inside of one mesh.

  • Good call @MrZak it is Z-Fighting, If you post this as an answer, I have an animated GIF to prove it on this blend you can steal to put in your answer if you'd like - The Link to the GIF. – Rick Riggs Mar 25 '16 at 22:05
