Unsolved Qt::AA_EnableHighDpiScaling stopped working in 5.13.0?
-
My application stopped using high dpi pixmaps in QWidget and antialiasing in QGraphicsView after upgrading to Qt-5.13.0.
Qt::AA_EnableHighDpiScaling
seemed to work in the past, but has no effect now, even though I am setting it prior to QApplication creation. Antialiasing in QtQuick seems to work fine. -
Pixmaps are rendered with low dpi and QGraphicsView antialiasing quality has drastically reduced on High-DPI displays and disappeared all together on Low-DPI displays.
First screenshot is from low-dpi display and second is from high-dpi (Apple retina) display. Pixmaps should be very sharp, QGraphicsView paths should be high-quality antialiased.

@patrickkidd May be this works: https://doc.qt.io/qt-5/qgraphicsview.html#renderHints-prop ?

Thanks for the idea, though I'm already doing that, and it wouldn't account for the low-dpi pixmap rendering.
