Smart Chat Background
by Barn0
Smart Chat Background sizes the chat backdrop to the longest line of each message, with configurable right-side padding and an optional blur.
What it does
The mod changes the background drawn behind chat messages. Instead of a fixed box, the backdrop is sized to the longest line in the message, so short lines stop sitting inside a wide empty panel. A separate slider sets the padding on the right side, and a smart message background option in the chat settings turns the sizing on or off.
An optional blurred chat background is included, and its strength can be tuned across a scale that runs from light to heavy. The blur is confined to the message area and follows the width set by the smart background, so the effect does not spill past the messages. The mod runs on the client alone and is published for Fabric across four release versions, 1.21.1 – 1.21.11, under the MIT License. The code is not open source. The Russian and English languages are included.
