I never understand these drive-by comments. It's not like developing on/for the competition is any easier or less convoluted. The author is debugging a cross-language (both managed and native), cross-architecture video game with a variety of third-party libraries.

Turns out that the Windows graphics stack is complicated (mainly because it needs to support a variety of closed-source programs that never saw maintenance after initial release), so compatibility layers meant to optimise for certain programs (an easy optimisation, frankly) accidentally caught the author's program in the master list, too.

There are people who actually try to implement better APIs. (We can quibble over effectiveness all day long. Sadly, it looks like a losing battle.) This is the only way to find them.
