No karajorma, I like to find out about bugs that are not absolutely show stopping after I've loaded through everything.
I love the idea even more of _in-game_ pop up's rather than "let's disjoint your perspective entirely by switching you into your desktop just to tell you about a missing frame.".
Yes, an error log on debug builds is essential, that is what debug builds are for. Absolute "the game is horrendously broken" should obviously indicate that to you, but again, if the majority of what your getting are the "hey, where'd my frame go?" messages, I'd prefer to read about later.
