Identity plate looks pixelated in the slideshow unless "Render in Background" is UN-checked. Does not happen when you export to video. The bug was present in version 2015.7 and 2015.8 on Mac 10.11.6

Can you send me the name of the font, the size you've chosen and a screenshot showing me the approximate size of the Identity Plate on the slide layout?
