This issue is now being tracked in a new ticket: UE-42280
This is a new ticket for the D3D 'HUNG' crash originally reported in [Link Removed]. Some fixes were introduced in 4.14.2 that decreased the occurrences of this crash, but other cases are still ongoing. The original Jira ticket has been closed for the cases that have been fixed.
This crash is hardware dependent, and although it occurs frequently for many of our users, it has been challenging to reproduce internally.
Repro steps currently under investigation
