Suppress OpenGL Error 128 Mod (1.21.4, 1.20.1) – Clean Up Your Logs

Suppress OpenGL Error 128 Mod stops Minecraft from spamming the log with the infamous OpenGL debug error:

OpenGL debug message: id=1280, source=API, type=ERROR, severity=HIGH, message='Error has been generated. GL error GL_INVALID_ENUM in (null): (ID: 173538523) Generic error'

When you use the Overwolf FPS overlay, this message can appear thousands of times per run, cluttering your debug log and making real issues harder to spot. The mod hooks into net.minecraft.client.gl.GlDebug and uses a mixin to filter out any OpenGL debug log entries with id = 1280, effectively silencing this specific error while leaving all other debug messages intact.

Features:

• This mod prevents the OpenGL GL_INVALID_ENUM error from being logged more than once. If you know what that is, this is probably for you. If not, don’t worry about it. This is a tool for people who read the debug log (mainly developers).
• It also suppresses GL_INVALID_VALUE and GL_INVALID_OPERATION.
