High DPI Session at Qt Contributors Summit 2019
Topics
- Icons always blurry/scaled with fractional factors in QPixmap QIcon::pixmap(QWindow *...) const qicon.cpp:899 , (Milian W to report bug), fix it to always downscale?
- Alternative proposal to fix blurry icons: Use fractional factors only for fonts. For icons, choose closest match and have layout adapt size?
- Tor Arne: Concerns about complexity ; Wayland and macOS have scaling built in whereas Windows/Linux require Qt handling. Move scaling code to QPlatformWindow, etc?
- David Edmundson: QML Image's sourceSize property is buggy/misleading, clarify docs at least
