What it does
Shut Up GL Error is a client mod by jamalam. Its job is narrow. It controls what Minecraft writes to the log when OpenGL reports an error. The project's own example is an invalid keycode report, a block of text under a "GL ERROR" banner that reads "Invalid key -1" with the code 65539.
If you've ever scrolled through a log and found that same block over and over, you know the problem. This mod is aimed squarely at that noise.
Logging modes
The mod has three behaviors, and you pick one in its configuration.
The default is to silence errors completely. Nothing gets written.
The second option logs each error code once. You keep a record that something happened, but you don't get the repeats.
The third option logs errors every time they occur. That's useful if you want the full stream back while you track something down.
The sources don't describe how or where the config is edited, so check the mod itself after installing it.
What it doesn't claim
The project talks about logging and nothing else. Honestly, it states no speed gain and no frame rate figure. The Modrinth listing files it under Game Mechanics and Performance, but those are category labels, not measured results. Treat it as a log cleaner.
Who it suits
It's a fit for anyone who reads their client log and is tired of seeing the same error again and again. If you never open the log, you probably won't notice it's there.
Compatibility
This is a client mod. Client side is marked as required and server side is marked as unsupported, so it belongs on the player's game and not on a server.
Two loaders are listed: NeoForge and Fabric. Nothing else is named, so don't assume support for any other loader.
The supported Minecraft versions are 1.21.11, 1.21.10, 1.21.9, 1.21.8, 1.21.7 and 1.21.6. Those are the six versions the project lists. Don't read that as a promise for anything outside the list.
License
The mod is released under the MIT License. The source code is public on GitHub in the JamCoreModding repository, so you can read what it does before you install it.
