We use wxWidgets as base window library... wxWidgets uses win32 api controls for windows... Visual Studio is an UWP app != win32 app. Blender uses its own window framework and uses OpenGL to draw it (this is bad for example for blind people, because this means there is now scree reading support). I do not know what Studio One 4 is and what framework it uses, but for sure it does not use the native win32 controls as wxWidgets does....
So win32 is to blame for this....
