--- Comment #2 from Tobias Deiminger <haxtibal at posteo.de> ---
I can reproduce exactly what you described in a dual monitor virtual machine.

> But the explanation given there claims that the height method would give me the height of the complete virtual desktop
If you refer to "Read
[https://doc.qt.io/qt-5/qdesktopwidget.html#screen-geometry] for details...",
there they say: "for desktops with multiple screens, the size of the desktop is
the union of all the screen sizes". That's not too explicit, but my guess is
that "union" means not the same as "complete virtual desktop". It's probably
more like with variables in a C-union, i.e. not laid side-by-side, but each put
at the same starting location and then measure the bounding rect. But again,
that's no real explanation.
