I have not called -[NSWindow acceptsMouseMovedEvents]. My custom view implements -[NSResponder mouseMoved:] but the frameworks never call this method during a mouse drag. My custom view implements -[NSResponder mouseDragged:] but this has never caused any problems. When I turn on custom logging for mouseDragged: I get following output. Mouse Dragged Rate: 125.7 events per second Mouse Dragged Rate: 124.1 events per second Mouse Dragged Rate: 124.2 events per second Mouse Dragged Rate: 124.8 events per second Mouse Dragged Rate: 125.2 events per second Mouse Dragged Rate: 124.6 events per second Mouse Dragged Rate: 168.3 events per second 2018-03-30 12:58:01.798960-0600 Xsolid[72930:1753914] Detected potentially harmful notification post rate of 112.994 notifications per second This is confusing because several years ago I turned on custom logging and recorded that AppKit would throttle NSLeftMouseDragged events to a maximum of about 60.0 events per seconds but that obviously is not the case now. To try and track down the problem I implemented notification logging by swizzling the following methods. -[NSNotification postNotification:] -[NSNotification postNotificationName:object:] -[NSNotification postNotificationName:object:userInfo:] Here is the output when dragging with the mouse in the custom view. I manually formatted the output with blank lines after the fact to make it more readable.
