Wrong device pixel ratio when automatic High DPI is set

Qt uses a device pixel ratio of 2 instead of 1 on a 14" laptop with a screen featuring a resolution of 1920 x 1080 px and a pitch of 157 dpi.

Qt reports Screen.pixelDensity = 3.1

Screen.desktopAvailableHeight and Screen.desktopAvailableWidth looks suspicious (525 960)
