No matter what shaders I use, none of them work. I always get some kind of GL errors.

Some information:

- Kubuntu 19.04
- AMD RX 480 (4 GB)
- Mesa 19.0.8 drivers
- Minecraft 1.14.\w Optifine 1.14.4 (from official site)
- Continuum 1.14.4 shaders
- Oracle JRE 1.8.0
- Official Minecraft launcher

Possible solutions:

- Use official AMD drivers
- Use different Java version
- Pray for god


- A lot of GL error messages are shown in chat
- Visual glitches or black screen with only UI
- Crashes when using 1.14.3 Optifine (won't even start)

Installation progress:

- Downloading Optifine installer from **
- From the installer selecting "Install" and installing it to my minecraft folder (/home/mx007/.minecraft)
- Starting the vanilla launcher, selecting the new Optifine profile & launching the game
- Moving shaderpacks to ".minecraft/shaderpacks" folder
- Enabling the shaderpack (When required: setting the required settings for that shaderpack)
- Joining my singleplayer world
- GL errors & visual glitches appear

I don't want to change Minecraft version to anything other than 1.14.*. I tried 1.14.4 and 1.14.3 myself, neither of them worked.

Probably because you have only 4 gigabytes of ram, Minecraft can barely run on that, let alone with shaders. Also, get an official Operating System, Linux is very buggy as it is an open source browser and is unstable on some builds.

Posted log contains no GL errors.

Also I will add that other games (but only a few) also have problems with graphics/shaders.

Then this is not a Minecraft problem and there is nothing we can do on Planet Minecraft.

Consider posting on Maybe the users there wil recognize the problem you are having.

Why you trying to use optifine 1.14.4 on minecraft 1.14, use the 1.14 version instead

That's a typo. Oops.

Also I will add that other games (but only a few) also have problems with graphics/shaders. The problem could be in the drivers but I'm using the Mesa drivers as they offer great performance and are widely supported. The official drivers are not released yet but there are some sketchy workarounds I could try to make them work. I will give them a try whenever I have time.
