I solved this already, but basically I was getting java.io.EOFException while installing Forge. From the (scarce) other forum postings on this, I needed to either clear the temp directory or delete some folder in `.minecraft/libraries`.  The other forum posts were for Windows, so I have no idea what temp folder they mean exactly, I doubt it is `/tmp`.  If someone can clarify where the download cache is for the Forge installer on Linux, that would be really nice.   Solution: In terminal, `cd` to your `.minecraft` folder, likely this command is what you want: `cd ~/.minecraft`. Run `find -name '*1.20.1*'`, or replace 1.20.1 with the version you're installing.  This shows where the damaged files might be which cause this error. Very carefully, determine which folders are safe to delete with `rm -rf`.  The commands I ran were: rm -rf ./versions/1.20.1* rm -rf ./libraries/de/oceanlabs/mcp/mcp_config/1.20.1* rm -rf ./libraries/net/minecraftforge/fmlcore/1.20.1-47.3.22 rm -rf ./libraries/net/minecraftforge/forge/1.20.1-47.3.22 rm -rf ./libraries/net/minecraftforge/mclanguage/1.20.1-47.3.22 After this I reran the install and it worked fine.

Hi everyone, I’m working on creating a UI similar to the one shown in the picture below. Most of the functionality is working perfectly, but I’m struggling to achieve a smooth blur effect for the background. Currently, I’m rendering the black transparent box using: "Gui.drawRect();" While the rest of the elements work as intended, the blur effect either drastically impacts performance or doesn’t look smooth at all. I’ve tried implementing the classes from Github, but I can’t seem to achieve the desired results.   I’d greatly appreciate your guidance or tips! Thanks in advance for your help! (This is on the hud no opened gui or something)
