QObjectPicker works on Linux, does not work on Windows

I have the same code running on two different devices. One runs Ubuntu 22.04, the other runs Windows 10. I have a set of entities loaded into a scene within a Qt3DWindow which has been containerized as a widget within a larger UI. On Linux, when I click on an object, the signal for the QObjectPicker is received and forwarded properly. On Windows, I do not get the same signal.

To elaborate on this: I have many entities which are created in a scene. Each entity has to it a QObjectPicker. This is all done by-the-books, so to speak, based on examples provided by Qt.

The main Qt3D window is made into a Widget via the createWindowContainer function. This allows the Qt3D system to be passed around as a standard widget, which is the desired functionality given that everything is being done in C++ and there is no QML being loaded. Additionally, I am not messing with the QObjectPicker settings, nor am I changing the defaults in the singleton renderSettings()->pickerSettings(). This seems to work pretty seamlessly on Linux, that is when I click the object the proper signal is fired throughout the system. On Windows, nothing happens.

Looking more closely into this issue, there was a place on StackOverflow where someone mentioned that the ingestion of a mouse event differs between the two operating systems on this exact issue, however nothing allows the Windows version to work despite the numerous different solutions I tried.

Any ideas would be greatly appreciated.

Can I bump this by commenting? Let's find out. Problem still isn't solved and undermines the very core of why one would use Qt to begin with.

Hi,

Which version of Qt are you using ?
Can you provide a minimal compilable example that reproduces your issue ?
