At the moment, I've only seen it on Xbox, but resource packs and maps with custom cubemaps at the current moment absolutely ruin the sky, and my eyes. And I'm not just talking about packs from like. Mcpedl. Even official downloads like The Legendary Phoenix have this awful bug.

It's this blinding white overlay ontop of the actual sky with little black (or corrupted) streaks as seen in the examples. The real sky is just pure black, even in the daytime. The sun, moon, stars, and sometimes clouds are still visible, though.

Steps to Reproduce:
1. Download map/resource pack with custom cubemap
2. Load it in
3. Observe the sky

Observed Results:
The sky is black with a white overlay

Expected Results:
Colored sky and properly rendered cubemap
