only if you resize it?
to me in that video the chrome icon was just resized bugger than what icon pixmaps are available, so blurring the icon is everything we can do and the normal behaviour

No. It happens with ALL icons... and you don't even need to resize them. 
Just add any icon on your desktop outside of the folderview and change the position/angle of it. It always blurs when it should be clear

due to QGraphicsView doing all rotations in software but after the application has actually done the painting, there are large aliasing artifacts on rotation. there is nothing we can do about this, it requires improvements in Qt.
