Bug Description

On Steam Deck hardware specifically, there are green lines appearing on screen/Missing Bloom effects. There are performance dips (into single digit FPS) on large levels but currently without enough evidence to know if it's due to it's weaker hardware or because of an error not listed here. Steam Deck Tested on Linux/Windows 10 OS with same result. When tested on a separate desktop PC these errors do not display.

Steps to recreate:

1. Launch Game through Xemu on Steam Deck.
2. Errors display on start screen and beyond.

Expected Behavior

Game should display a clear screen correctly with Bloom effects and without performance issues.
