The game freezes on Intel HD 2500 since 1.21.6

Short description

Minecraft 1.21.5 launches correctly on my Intel HD Graphics 2500 system. Starting with 1.21.6, every tested version freezes on the Mojang loading screen and Java becomes unresponsive.

Steps to reproduce

1. Use a Windows 10 PC with Intel HD Graphics 2500.

2. Launch Minecraft 1.21.6 or newer.

3. Wait for the Mojang loading screen.

Expected result

Minecraft finishes loading and reaches the main menu.

Actual result

Minecraft freezes on the Mojang loading screen. Java becomes unresponsive and Windows reports "OpenJDK Platform binary is not responding."

Additional information

Tested with:

• Official Launcher

• Prism Launcher

• FastClient

• Vanilla

• Fabric

• NeoForge,etc

Minecraft 1.21.5 always launches correctly.

Replacing Intel's OpenGL implementation with Mesa3D 25.1.3 by placing opengl32.dll and libgallium_wgl.dll beside java.exe allows Minecraft to launch every time. Performance becomes very low because Mesa uses software rendering, but the startup freeze disappears completely.

This suggests the problem is related to Intel HD Graphics 2500 OpenGL driver initialization introduced in Minecraft 1.21.6 or later.

Additional information:

I have attached two different latest.log files:

• One is from a failed launch using the Intel HD Graphics 2500 OpenGL driver.

• The other is from a successful launch after replacing the OpenGL implementation with Mesa3D 25.1.3 by placing opengl32.dll and libgallium_wgl.dll beside java.exe.

The successful launch uses the same Minecraft version and Java installation. The only change is replacing the OpenGL implementation with Mesa, which strongly suggests the startup freeze is related to Intel HD Graphics 2500 OpenGL driver initialization.
