The user is reporting that, on their iMac, Whenever _AMDDeviceDetached event occurs in the Activity Monitor, the editor hangs utilizing a reported 101% of the CPU.
*The user claims this is 100% reproducable if you can get an "AMDDeviceDetached Event" to occur in the Activity Monitor. However, I was not able to force this event on our MacBook Pro given the user's repro steps.
The user gives repro steps, but any event that causes an AMDDeviceDetached event to occur in the Activity Monitor allegedly causes the Editor to hang for long periods of time:
The steps the user gives to cause this are as follows:
1. On an iMAC, Connect an iOS Device.
2. Launch an Unreal project to an iOS device
3. Disconnect the iOS device by unplugging lightening/usb cable.
4. click import (or any event triggering dialog) to launch file open dialog.
RESULT: The engine freezes for an extended period of time
EXPECTED: The engine to continue to run normally
