I have two monitors connected to my Mac. The two have different resolutions. Dragging APP between the two monitors is OK and would not cause troubles.
On the other hand, APP would crash when I turn one monitor (the one with APP) off and the system forces APP to move to the monitor that’s on. The forced movement between monitors works totally fine for all my other applications. All of them get pushed to the monitor that is on smoothly, and only APP crashes. I can’t tell whether the crash is triggered by the forced movement, or by the difference in screen resolution, as I do not have two screens of the same resolution.
Cheers,
