Description

This is a frequent D3D Hung crash, similar to [Link Removed] and [Link Removed].

A potential fix for the other crashes was released in 4.14.2, but this crash is still occurring on that release.

Steps to Reproduce

Stephen - Repro steps currently unknown. I did experience this once on my home PC after dragging a few static meshes from the Infinity Blade pack into my level and starting to rotate one of them.

Alternate User Provided Repro:

A user reported that switching to wireframe view mode caused the crash.
