Steps to reproduce:
1. Download and open the project "Graphics Jobs Bug.zip"(ownCloud link)
2. Build a Development build for Standalone
3. Play the build
4. Go near the Outhouse

Result: Graphics artifacts around the particle system (smoke)

Reprpoduced on 5.5.0f3, 5.5.0p3
Due to project size and extensive scenes, unable to test for regression.
However, user notes this started happening when they upgraded to 5.5, therefore
Bug first introduced in 5.5

Notes:
-Unable to reproduce this on a regular build, but user noted that it does for them
-5.6.0b3 seems to not have this issue, though crashes when trying to build a regular build
-No small scale reproduction is possible
-Sometimes artifacts appear not just on the outhouse smoke, due to the whole scene being in a snowstorm particle system
-User notes this is reproducible on both Xbox and Standalone builds, though not on PS4
