on macOS you can open 'System Preferences'->'Accessibility'->'Zoom' and then select zoom style and check use keyboard shortcuts to zoom. I used 'puzzle' example from Qt examples to test drag and drop and got unusable behaviour when zoom style set to 'Fullscreen' (mouse pointer jumps to the point from where I turned on zoom feature and it's impossible to move it). When zoom style set to 'Picture-in-picture' everything works fine. How to fix drag and drop when zoom set to fullscreen ?
