One keybind change in Java 26.1.2 removes all movement restrictions while your inventory screen is up. The clip circulating on X shows players running jumping and attacking without closing it and the multiplayer implications are obvious and ugly.
Minecraft’s latest version dropped another how-did-this-ship moment. Players discovered that by simply changing one keybind you can move around completely normally with your entire inventory screen open. No exploits no resource packs just a straight up oversight in 26.1.2.
How obviously broken it is
The video from this X post shows smooth movement inventory management and combat all at once. In a game where opening your inventory is supposed to leave you vulnerable this flips the script entirely. PvP servers are already testing it and the results look exactly like the kind of cheese you would expect.
- Rebind the debug menu key in controls
- Open inventory and the movement keys still respond
- Works in latest Java release 26.1.2
- No mods required just a settings change
- Already spreading on multiplayer servers for PvP and griefing
The bug does not appear in official patch notes which means it slipped through or was introduced in a recent snapshot. Community reaction on X is a mix of laughter at how dumb it is and immediate theorycrafting on how to abuse it in anarchy style servers or SMP events. One post called it a major bug and the attached clip proves the point without exaggeration.
現在のMinecraft Java版(26.1.2)では、インベントリを開いていても、移動できてしまう重大なバグがあるらしい…！！
Whether this gets patched in the next snapshot or lingers depends on how fast Mojang acknowledges it. In the meantime expect clips of players kiting withers or winning fights while sorting chests. The multiplayer scene never sleeps and this kind of oversight feeds directly into the chaos players love to exploit.
