Description
When showing a tooltip it can crash when querying the QScreen for the handle(). This happened in Qt Creator and crashed with the following:

The steps to reproduce are not certain, I suspect that it can happen when showing the tooltip for the project/config selection near the bottom right (above the big play button)
