How to fix the issue?

Ensure that you use your computer with administrator privileges and have a working internet connection, and then start following the methods below to resolve the issue.

Remove all shaders

Shaders in Minecraft are like special add-ons that let players change the look and feel of the game, such as turning winter scenes into summer landscapes. However, shaders can sometimes clash with other mods because they use many of the game’s resources.

To fix the error message you’re seeing, try disabling the shaders individually. Start with the most recent one you added and see if that solves the problem. If not, try disabling the next one, and so on. If you want to keep the shaders for later use, you can cut and paste them to another location on your computer.

Update OptiFine

OptiFine is a helpful tool for Minecraft that improves how the game looks and runs faster. It supports HD textures and provides configuration options necessary for using mods. It can boost your game’s frame rate and allows you to use shaders for better visual effects.

To fix any issues, check the version of OptiFine you have installed. If it’s an older version, go to the official OptiFine download page and install the latest version. After installing, restart your computer before launching the game again.

Check Mods version compatibility

Users encountering OpenGL Error 1281 in Minecraft have heavily modified the game and are using multiple mod modules. This error can occur when the versions of different mods are not compatible with each other, or they are out of sync.

To fix this, carefully check all the mods you’ve installed and their versions. If you find any mismatches, disable the mod causing the issue and try launching the game again. You can find information about mod compatibility on the official developer website of each mod.

Reinstall Minecraft

If none of the above solutions works, consider reinstalling Minecraft. Uninstall the game completely, including all related files and folders. Then, download the latest version from the official Minecraft website and install it afresh. Remember to back up your game saves and worlds before performing a reinstallation.
