AFAICT, this doesn't seem to fix the performance issue of the modern Windows UI, even though it claims so. I've always been saddened by the modern Photos app taking several seconds to boot, compared to the good ol' Picture and Fax viewer taking a blink. Considering this brand new UI toolkit is just a rehash of the framework Microsoft were using internally, and probably also used by the Photos app, how can we expect to gain a performance boost from WinUI, when they cannot fix the performance issue of their own apps?
