Artifacts Appearing On Screen, Apparently Behind All Rendered Terrain

Getting a Strange artifact where distant horizons terrain appears as shown whenever I look at the sky, or rather whenever no terrain is obstructing it. It appears to be static, though I'm not entirely sure. I am currently using Oculus 1.4.7_DH compatible, which I got from here: https://github.com/PlxelBuilder/Oculus-1.16.5-DH-Support/releases/tag/Release. I am currently using 2.1.0a for DH, and the shaders I am using are Complementary Reimagined, though others shaders such as BSL have the same issue. Setting transparency to Complete does not help.
