The presentation format recording scripts use the xc module (which stands for "Constant Color" to generate placeholder images for slides which are missing / failed to convert and a few other circumstances. The XC module is safe to enable, since it doesn't involve reading any files - it only generates single-color in memory images, and image sizes (memory usage) are limited by other sections of the policy.
