Description
In Qt < 5.14, the platform plugin would provide the devicePixelRatio value via the QPlatformScreen::pixelDensity() implementation.
In Qt 5.14, the devicePixelRatio value is computed in QtGui based on QPlatformScreen::logicalDpi().
This caused a regression since QXcbScreen::logicalDpi() reports a single logical DPI value for all screens based on virtual desktop geometry, while pixelDensity() computed its value based on individual screen geometry.
