This can be generallized to Transformation Persistence selection issue.I checked that this issue just occur on ios, it works on Mac, windows, Android. |

Current implementation of Transformation Persistence knows nothing about virtual resolution used in macOS/iOS APIs. So that when actual rendering resolution is twice/trice larger than virtual resolution of mouse movement events, they do mismatch. This is not an issue for picking normal objects, as their sizes are independent from rendering resolution. To workaround this limitation, you have to provide (convert) mouse movement events to AIS_InteractiveContext::MoveTo() in real rendering resolution, and implement Aspect_Window::Size() returning rendering resolution (Cocoa_Window currently does not). |

I have uploaded the update file Cocoa_Window.mm. The function Cocoa_Window::Size() and Cocoa_Window::Position() update accordingly.Is there any other codes need to be updated? |
