This is a surprising opinion to encounter, given my experience with scaling on Windows, where simple things like taking my laptop off its dock (going from desktop monitors to laptop screen) causes applications to become blurry, and they stay blurry even when I've returned the laptop to the dock. Or how scaling causes some maximized window edges to show up on the adjacent screen. Or all manner of subtle positioning and size bugs crop up.

Is this more of an aspirational thing, like Windows supports "doing it right", and with time and effort by the right people, more and more applications may be able to be drawn correctly?

[edit] I guess so, I see your comment about setting registry keys to make stuff work in Microsoft's own programs. That aligns more closely with my experience.
