Lithium seems to be fairly good in terms of rendering our advanced epubs, but it's not perfect; note especially that it doesn't invert black-and-white SVGs correctly so unless you set it to a dark page theme, they'll be "invisible". There are also some other rendering quirks for things like very big tables used for play formatting. Poor renderers are a perennial problem in the epub world and there seems to be little interest in improving the situation. Just use the compatible epubs - for reading purposes they're almost equivalent except in some rare edge cases. Or, you can use our 'read online in browser' option to read ebooks directly in your web browser, which will serve you the source of our advanced epubs. But of course reading in a browser is less than ideal.
