RPi3, WebView locks the mouse, while keyboard works fine

mewster

I'm trying to dinamically open and close a web view, using

LayoutVerticalMain->addWidget(&WebView);
WebView.load(QUrl(url));
WebView.show();

and

WebView.hide();

.
On the main.cpp I called

QtWebEngine::initialize();

before the

QMainWindow::show()

The view opens fine, but when I move the cursor over the WebView, the mouse "stops" at its border, without entering. If I use the keyboard's tab key to navigate the page, it works fine. Any clicking in any internal area seems to be ignored.

I'm using QT 5.12.0 on a raspberry Pi3, cross-compiled from a Ubuntu 16.04.

Did I miss any requirement, or skip some configuration?
Thanks.

Update: it seems that calling the setUrl on the constructor of the QMainWindow the page works fine; if I call the method later (even just before the main window .show() method) the repaint events don't get called
