Defamation and blasphemy of the highest order. In XP the GUI was fully hardware accelerated and highly performant. Possibly the most perfect thing to have ever been created. In vista this was all torn out and replaced with software rendering that ran like treacle. All for a transparent window gimmick.

Are you talking about the compositing? I haven't used Vista, but I definitely remember that in Windows 7 you couldn't use the glass theme unless hardware acceleration was working, because it relied on compositing on the GPU.

Windows XP supported partially transparent windows, but I'm not sure if this required hardware acceleration or there was also a software rendering fallback.

ah yes, the most perfect thing to ever exist: https://i.imgur.com/X5BzWQj.jpg

there's plenty of things I don't like in newer windows versions, but the introduction of compositing is not one of them
