Re: [gentoo-dev] Re: Should there be a preference with qt4 and qt5 USE flags?

[Jason A. Donenfeld]

If qt5 is set as a USE flag, it should be preferred over a qt4 USE flag.
The use explicitly opted in.

Also, most software that does run with Qt5 runs better with Qt5, and
supports numerous features such as better HighDPI support.
