Re: Enabling blur in kwin slows down the desktop effects
I've seen KDE/Qt devs point fingers more than enough (not only to NVidia).
They're not wrong, ever. Everyone else this. If something is done in accordance with a specification, it Must Work, and it is irrelevant if all major implementations actually don't support it well.
OK, I exaggerated a bit, but you get the point. I hate this kind of ignorance.
