Visual bug

Hey guys,

I have a strange visual bug (some sort of flickering cubes) in unreal 4.14. The problem that this bug also appears on high res screenshots. Do anyone know how to solve this problem? Sorry if my question is dumb, but I am still in a learning process and have this problem in every tutorial scene.

Hi Yakmark,

Can you post your system specs or DxDiag if you’re on windows? I don’t see the same issue when I open this same map on my machine, so hopefully if it’s a system specific thing it’ll be more noticeable to see what’s going on.



Hi Tim,

Thank you for quick response! Here is my system specs:

macOS Sierra
Version 10.12.1

MacBook Pro (Retina, 15-inch, Late 2013)

Processor 2.3 GHz Intel Core i7

Memory 16 GB 1600 MHz DDR3

Graphics NVIDIA GeForce GT 750M 2048 MB,
Intel Iris Pro 1536 MB



Thanks, Mark!

We have the exact same machine for our team. I was able to reproduce this and submitted the ticket here: Unreal Engine Issues and Bug Tracker (UE-39865)

Looks like the issue is from having multiple reflection captures overlapping that is causing the artifact.


Thank you, Tim!
