NoGhostBlock

by MrLisick

NoGhostBlock fixes ghost blocks, the leftover block outlines that linger after a server rejects a break, by resyncing them with the server.

FabricClient required, server optionalAll rights reserved1.21.1 – 1.21.11

What it does

Ghost blocks appear when the client shows a block as broken or placed while the server has not confirmed the change. NoGhostBlock corrects the client view so it matches the server again. The mod is built with Java 21 and uses Mixin hooks to keep its effect on frame rate small, and it avoids extra network traffic.

A command registered through the Fabric Command API lets players run the ghost resync on demand, which covers situations where the automatic correction is not enough. The mod runs on vanilla servers, Realms and large networks, because it does not change server behavior. Only the client needs the mod to be installed.

NoGhostBlock is published for Fabric only, with files covering 1.21.1 – 1.21.11 and 1.0.0 for 1.21.11 as the latest build, dated 2026-04-17. The code is available as public source, and the mod is not open source; it is released under All rights reserved.

Key features

    A command, registered through the Fabric Command API, triggers the resync manually for stubborn cases.

  3. Mixin-based hooks

  4. Vanilla server support

    Works with vanilla servers, Realms and large multiplayer networks without server-side changes.

What the author says

🚫 NoGhostBlock (Fabric) Хватит сражаться с невидимыми блоками. NoGhostBlock — это легкий клиентский мод, решающий одну из самых раздражающих проблем в мультиплеере Minecraft: «фантомные блоки» (рассинхрон между клиентом и сервером).
