Portal GUI Fix
by SeishiroNagi
Portal GUI Fix repairs a bug where the portal transition overlay stays on screen after a player travels through a nether or end portal.
What it does
Once a player has crossed a nether or end portal, the transition overlay in vanilla 1.21.1 may stay on screen and hide the blocks beneath it. The mod corrects this broken transition GUI, which is tracked as the well-known bug MC-2071, and restores the vanilla behavior so the overlay clears as intended.
The fix is a small client-side change, so it adds nothing to the server and needs no server installation. Players add it to their own install and need no extra setup. It is built for Fabric, Forge and NeoForge across five release versions, 1.16.5 – 1.21.1, under the MIT License, and it is not open source. Fabric installs require Fabric API, and the Fabric Loader must be 0.16 or newer.
Key features
Overlay cleanup
The stuck transition overlay clears after a player travels through a portal, so the screen is no longer blocked.
Vanilla behavior restored
The portal transition returns to the behavior the vanilla game intends, rather than keeping a leftover screen.
Minimal configuration
The mod needs little or no setup, and it works without changing how the game plays on the server.
Compatibility
Latest build for each game version and loader.
Only full game releases are shown. This mod publishes no snapshot builds.
Use cases
Playing nether and end travel
A player moving between the Overworld, the Nether and the End sees the transition clear normally after each portal.
Single-player and multiplayer clients
Clients on any server can run the fix, because only the client changes its portal screen.
Who it’s for: Players on Minecraft 1.21.1 who run into the portal transition bug, on Fabric or Forge, and want the vanilla portal screen back on their own client.
How it compares
No Dimension Background is a Fabric-only client mod for 1.20.5 – 1.21.11, released under CC0 1.0 Universal and open source, so it targets a different portal screen issue. TieFix is also Fabric-only, open source under the GNU Lesser General Public License v3.0 only, and covers 1.18 – 1.20.1, which is an older range than this mod.
