## Not required in 24w11a and above!
**Note: This resource pack requires a full game restart to load correctly. A restart is also required after disabling the pack.**
Improves the blur algorithm used in 24w09a's new GUI.
The vanilla blur algorithm uses an unweighted average of surrounding pixels, which produces a blocky appearance (especially look around the hotbar):
This resource pack slightly modifies the algorithm to reduce the weight of further away pixels, which produces a much nicer blur effect:
This is the entire patch to the vanilla blur shader:

// Accumulate smoothed blur
float strength = 1.0 - abs(r / Radius);
totalStrength = totalStrength + strength;
- blurred = blurred + sampleValue;
+ blurred = blurred + (sampleValue * strength);
}
- fragColor = vec4(blurred.rgb / (Radius * 2.0 + 1.0), totalAlpha);
+ fragColor = vec4(blurred.rgb / totalStrength, totalAlpha);
}
```
Given the `strength` and `totalStrength` variables are already in the vanilla shader but are unused, it seems possible that the blur algorithm was originally intended to be more similar to this resource pack.
