The licensee has reported that when you make a mesh extremely thin (e.g. z = 0.0001), it can cause emissive materials applied to the mesh to flicker.
Grab the licensee's repro from here - [Link Removed]
Open the level "EmissiveTest"
The yellow light source will be shuddering/flickering.
If it is not, move very slightly to either side of it and it should start flickering.
There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-115697 in the post.
