I have the solution to this problem! What you need to do is find a different SD card, inhumanely dispose of your current one, and use the new SD card, and voila! Problemo solved!

Okay, I'll be serious. You were obviously using the color white and brushing on the canvas to provide playback. You can press 'R' or 'L' depending on the control scheme to open up the color wheel. Or you could follow my advice that I said above. I don't particularly appreciate trolls.
