When a QAxWidget is a sibling with other widgets then it might be painted incorrectly where they overlap

When a QAxWidget is a sibling with other widgets then it might be painted incorrectly where they overlap. This does not always happen, and is only the case with QAxWidget being involved.

In the example, click on the button and then the next button that appears and there will be a overlay of a button on top of the QAxWidget that is shown.
