Does anyone know what this error message means (in Minecraft with Optifine)?
The game crashed whilst generating mipmaps for frame Error: java.lang.RuntimeException: Invalid image size: NativeImage [RGBA 16x16 @ 750321552N], sprite: TextureAtlasSprite {name = 'minecraft: missingno', frameCount = 0, rotated = false, x = 0, y = 0, height = 64, width = 64, u0 = 0.0, u1 = 0.0, v0 = 0.0, v1 = 0.0}
Did you insert any image anywhere or a texture pack?
It's up to Optifine.
Try another older version of Optifine for the version.
For example OptiFine 1.13.2 HD U E7
Ne just installed Optifine and wanted to start the version and then the code came
1.13 right?
Yes 1.13.2
Yes that is normal. It's such a bug. Everyone has.
Optifine version F5 right? Try E7 or an older version.
