Qt Creator 5.0.2
1. on a macbook pro without any external monitors connected, start QT Creator
2. connect a second display (in my case a DELL Ultrawide USBC monitor)
3. move QT Creator onto the second display
4. in QT Creator, load a project and right-click on the project or any of the filennames in the project
The popup context menu appears on the macbook display and not on QT Creator on the second display (where it should)
This bug has been around for a long time through QT Creator 4 and is still in 5.
FWIW after doing the steps above, there is a high chance QT Creator crashes completely after a few minutes of work.
If I connect the second display BEFORE starting QT Creator, the context menus appear correctly on the second display and the crashes don't occur.
