Description
QImage::scaled(,,,Qt::SmoothTransformation) in QT6 has spot noise or dither in the scaled output and looks bad. The same function in QT5 gives a smooth output.
The fourth parameter defaults to Qt::FastTransformation but I am using Qt::SmoothTransformation.
Screenshots from Qt6 and Qt5 are attached.
I have only checked on macOS but if the code is different on Windows, someone should check that also.
Please fix ASAP. I'm a Qt Commercial licensee about to re-release my products compiled with Qt6 and this bug is holding me up.
