5.12.7, 5.15.1
Description
OS: OpenSUSE Leap 15.2
DE: KDE Plasma 5.18.5 - Full Wayland
I have set my Screen Scaling to 150% as seen on the attached screenshot. In my application following code reports device pixel ratio of 2, expected would 1.5:
auto desktopWidget = QApplication::desktop(); return desktopWidget->devicePixelRatioF(); // returns 2, expected 1.5
Also, tested on Arch Linux running Sway Wayland and screen scaling set to 250%, following is reported:
DesktopWidget devicePixelRatio: 3 DesktopWidget devicePixelRatioF: 3 DesktopWidget logicalDpiX: 96 DesktopWidget logicalDpiY: 96 DesktopWidget physicalDpiX: 135 DesktopWidget physicalDpiY: 135 QScreen devicePixelRatio: 3 QScreen logicalDotsPerInch: 96 QScreen logicalDotsPerInchX: 96 QScreen logicalDotsPerInchY: 96 QScreen physicalDotsPerInch: 135 QScreen physicalDotsPerInchX: 134.532 QScreen physicalDotsPerInchY: 135.467 QWindow devicePixelRatio: 3
