Hi all,
I'm having some problem with my application where when I drag it from a HD monitor to a 4k monitor with 125% dpi scaling my application print error like:
QWindowsWindow::setGeometry: Unable to set geometry 640x480+3210+774 on QQuickApplicationWindow_QML_0/''. Resulting geometry: 1280x960+3210+774 (frame: 0, 0, 0, 0, custom margin: 0, 0, 0, 0, minimum size: 0x0, maximum size: 16777215x16777215).

Sometimes the window will resize to very large or very small sizes just by dragging it from one monitor to the other (OS Windows 10).
EDIT: I forgot to say but I have on my application:
QGuiApplication::setAttribute(Qt::AA_EnableHighDpiScaling);
QGuiApplication::setAttribute(Qt::AA_EnableHighDpiScaling);

Dpi scaling works fine until suddenly the problem happens after moving the window a couple of times back and forth.
Please see below a snippet of my code:
