After updating Minecraft to version 1.21.5, I started experiencing severe graphical issues. All item icons, the player model, and some UI elements appear bright red, distorted, or glitched. And makes the game non playable. This did not happen in version 1.21.4 or earlier.
I have tested this issue with:
No mods installed
Default resource pack only
No shaders
Updated GPU drivers
Clean reinstall of Minecraft
The issue persists in 1.21.5 and 1.21.6, but everything works fine when I switch back to 1.21.4.
I believe this issue is related to the graphics renderer change introduced in 1.21.5.
Screenshot of the issue and latest logs are attached. Please investigate.
Steps to Reproduce
Launch Minecraft version 1.21.5 or 1.21.6
Enter any world (singleplayer or multiplayer)
Observe item icons, player skin, and UI – they appear bright red and corrupted
Expected Result
Item icons, player model, and UI should render normally with default colors and shapes.
Actual Result
Textures appear red, distorted, or corrupted. The issue affects the entire inventory, UI, and skin rendering.
Environment
Specs:
GPU: Intel(R) UHD Graphics
OS: Windows 11 Pro
Java: default from launcher
Minecraft versions tested: 1.21.4 (works fine), 1.21.5 and 1.21.6 (broken)
