I put debug in Qt, in qmlscene it works as you'd expect. In the system settings case QQuickImage thinks the DPR is always 1. The relevant window is QQuickWindow(0x55f9aee446d0, visibility=QWindow::Windowed, flags=QFlags<Qt::WindowType>(Window), title="Offscreen", geometry=336,21 426x592) with window()->effectiveDevicePixelRatio() == 1 It's a bug in the window embedding. ---- I have a consistent rule about working round Qt bugs. I'll allow it if and only if we understand the root cause and have filed a bug or patch upstream and then reference it.
