Q: What kind of errors does this mod suppress?

Q: Which loaders are supported?

The mod supports Fabric, Forge, NeoForge, and Quilt.

The Shut Up GL Error Mod (1.21.7, 1.20.1) is a utility-focused mod that targets one of Minecraft’s most persistent annoyances: the endless stream of meaningless OpenGL error spam in the logs. These repetitive messages — often showing up as ########## GL ERROR ########## @ Pre render 65539: Invalid key -1 serve no practical purpose but flood the console, making real issues harder to detect.

This mod quietly filters out those irrelevant errors, helping developers, server owners, and modpack creators keep their logs clean and focused. It works on Fabric, Forge, NeoForge, and Quilt, offering broad compatibility across most modern modded environments.

Features:

Suppresses Repetitive OpenGL Errors:
Silences log spam caused by invalid keycodes or OpenGL render warnings that have no effect on gameplay.
Patches InputConstants Behavior:
Fixes how Minecraft’s InputConstants#isKeyDown handles invalid keycodes like -1 or 0, which are often the root of excessive GL spam.
Log Clarity for Developers:
Keeps your logs readable and relevant ideal for spotting real exceptions or performance-related messages.
Lightweight and Non-Intrusive:
Doesn’t change any visual behavior or in-game mechanics. It only improves the background log handling.
Multi-Loader Support:
Fully compatible with Fabric, Forge, NeoForge, and Quilt, making it useful in nearly every modding setup.
