Unfortunately, this scales after drawing. The entire point of hiDPI is to have a crisper image. To achieve that, the scaling must be done at the drawing level.

Unity and Gtk would scale everthing up, so things that are properly drawn before being re-scaled.

So quality will be there.

For normal/low-DPI screens instead, you'd scale everything down, so you'd lose some memory CPU power, but you'd still get the quality result.
