Application exe runs out of memory when resizing/maximizing

I'm running the snippet of code below. I'm on a 4k monitor with dpi set to 200%. Using the debug libs, as I resize the window back and forth and then hit maximize, I notice my free memory dropping by hundreds of MB at a time. If I keep doing this non-stop I eventually will run out of free memory on the main process. Sometimes the qtwebengineprocess will crash and I will get all the free memory back. Now if I do a resize then let the application sit, some but not all of the free memory comes back.

This also happens on a 1920x1080 screen with no scaling, but just at a much slower rate.

This also happens with the release libs as well, again at a slower rate.

#include <QApplication>
#include <QWebEngineView>

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);

    QWebEngineView view;
    view.setUrl(QUrl(QStringLiteral("http://www.qt.io")));
    view.resize(1024, 750);
    view.show();

    return app.exec();
}
