Created attachment 10059 [details] Notice the white squares within the normal light and tan squares. Chess boards when either rendered using the in-built GNU/Linux PDF renderer or using the wikimedia PDF renderer in wikimedia results in poor/inaccurate output.
Looks like source page is https://en.wikibooks.org/wiki/Chess/Tactics Seems that the PDF renderer is not handling transparent backgrounds for images correctly; each image gets a while background that covers up the tan or brown background already in the table cell behind it.
