QComboBoxListView is constructed without a parent. It therefore
inherits the current screen, which normally is the screen on which the
related QComboBox is located.
With two identical screens in Windows, that can lead to the popup
showing on the wrong screen. The issue occurs, when the other screen
is found before the right one.
This patch calls setScreen() in the constructor, to explicitly inherit
the screen from the combobox, if a valid pointer is passed.
