Scroll Fix

by kwahson

Scroll Fix changes how mouse-wheel scrolling is read on Linux Wayland setups, so that scroll input in Minecraft screens behaves more predictably.

NeoForgeClient-side onlyGNU General Public License v3.0 or laterOpen source1.21.1

What it does

On some Linux and Wayland systems, GLFW reports mouse-wheel deltas that make scrollable interface areas move much faster than the vanilla hotbar scroll. Before Minecraft screens and modded UI overlays see mouse-wheel input, the mod evens out those deltas, aimed at the specific problem of wheel scrolling on Linux Wayland. It is a client-side NeoForge mod for 1.21.1, so servers do not need it. The source code is public and the mod is open source under the GNU General Public License v3.0 or later.

Key features

  1. Normalized wheel deltas

    Mouse-wheel scroll values are scaled before they reach Minecraft screens, reducing overly large jumps.

  2. Overlay support

    Modded UI overlays receive the normalized scroll values, so their lists scroll at the same reduced rate.

  3. Linux and Wayland focus

    The fix targets setups where wheel deltas from GLFW cause fast scrolling, and it was tested on X11.

Questions

Does Scroll Fix need to be installed on the server?

No. Only the player's game needs it, and servers run without it.

What the author says

Client-side NeoForge 1.21.1 mod that normalizes mouse-wheel scroll deltas before Minecraft screens and modded UI overlays receive them. The target is Linux/Wayland setups where GLFW reports wheel deltas that make some UI scroll areas move far faster than vanilla hotbar scrolling.
