This pull request addresses severe visual rendering issues (such as invisible chunks and mesh corruption) that occur on AMD GPUs (e.g., RX 6600) when using Embeddium.
The root cause of these issues appears to be aggressive driver-level optimizations triggered by AMD's Windows drivers, which end up interfering with Embeddium's rendering pipeline.
Solution
This patch introduces a workaround by bypassing the problematic driver behavior. It accomplishes this by manipulating Windows API calls (Kernel32) to temporarily spoof the command line arguments. This successfully prevents the AMD driver from incorrectly applying its invasive optimizations to the game's rendering context.
Impact
Fully resolves mesh corruption and invisible chunk issues on AMD hardware.
The workaround is safely isolated to Windows systems running AMD hardware via specific API interactions.
wait so how do i do this because I'm on 1.20.1 forge and want to use anything but optifine
sup, there is a yt video, in the comments or description u can found the source code and a compiled version :)
