Description
If i move a frameless window with the startSystemMove() function from one screen (100% ratio) to another screen (125% ratio), and use the settings of ( QGuiApplication::setAttribute(Qt::AA_EnableHighDpiScaling) QGuiApplication::setAttribute(Qt::AA_UseHighDpiPixmaps)) it shrinks the size. Window (400x300) becomes to (300x225). (in this mode i have device-independent pixels) If i would use the windows system intern method for this, everything is fine.
Additionally startSystemMove is by far not smoove. Compared to our own implementation and how Windows is handling natively dragging windows the window is not following the cursor exactly.
