Please help me to solve a problem with run Minecraft. My hardware: CPU Intel Core I7-4790K (not overclocked), RAM 16GB, Video AMD R9-285 2GB, hdd+ssd. Operating system Xubuntu 17.04 / x64, file system ext4.

Minecraft version 1.11.2, Forge versions 1.11.2-13.20.0.2298, some parameters to run Java:

 

$tmp = </mnt/e/Games/Minecraft_Launcher>
java -Xmx4096M -Djava.library.path="$tmp/versions/Forge 1.11.2/natives" -cp "<very-very long string with all paths to all libraries>"  -Dfml.ignoreInvalidMinecraftCertificates=true -Dfml.ignorePatchDiscrepancies=true -Djava.net.useSystemProxies=true -Dfile.encoding=UTF-8 -Xms4096M -XX:+UseG1GC -XX:ConcGCThreads=8 net.minecraft.launchwrapper.Launch --username Lant --version Forge 1.11.2 --gameDir $tmp --assetsDir "$tmp/assets" --assetIndex 1.11.2 --uuid 00000000-0000-0000-0000-000000000000 --accessToken null --userType legacy --tweakClass net.minecraftforge.fml.common.launcher.FMLTweaker --versionType Forge --width 1920 --height 1080

 

While starting Minecraft, a hang appears on splash screen (see screenshot). Memory value on up and texture file on bottom constantly changing. In some cases all runs normally (~10%), game run normally, all mods working ok. But in other 90% cases game hangs up on splash. In system monitor I see a full load of one core of processor, task is looped and hangs. It only remains to kill a dead task.

 

I see a log files 'fml-client-latest.log', collect them all from various cases (run and hang) and store on directory with various numbers. On all logs I see a hang on string:

[23:09:40] [Client thread/DEBUG] [FML/]: Bar Finished: Texture mipmap and upload took 0.328s

On 'hanges logs' this string does not exist, but on 'normal runs' - exist.

 

I don't know what is it, but I think that it is some with memory allocations, some buffers overflows and some insufficient... Can you help me?

Second addition. I delete all mods. Upgrade Forge to 2299. Game starts only in ~10% cases, in 90% cases it's hang up.

Something with java options... I don't know where...

 

I have change my launcher file:

All libraries listed in alphabetical order. Java parameters separated to individual strings. What about game parameters?

 

In a log file last string before hanging:

 

[Client thread/INFO]: Created: 512x512 textures-atlas

And hang up after this. "Texture mipmap and upload" show various files in last string on bottom

(for example, minecraft:items/mutton_raw). Adding mods decrease probability of success run, I suppose that in this case there are more files load, and probability of hang is increase.

Okay, Error is detected. This is splash (drawing of splash)

 

I have disable a splash screen on 'config\splash.properties' file - and all work fine with all mods. 100% work without hangs and loopings.

Therefore this is a splash screen cause hangs. I suppose that drawing of status bar with very fast and quick listing of files in splash - cause game to hang. It's a need to some reduce splash screen updates, for example no more 5-10 times per second. How to do this? Create a some buffer where loading state saves, while game starts. DO NOT update a splash with these updates, update only this buffer. Start a parallel independed task which run 5-10 times per second to output buffer and draw a splash. Output made - task executed. And 5-10 times per second, absolutely independ to main process.

It has nothing to do with the speed of the splash updates, your screen renders it every frame anyways.

It's a issue with your specific graphics card/drive set that doesn't like multi-threaded rendering.

There isn't anything you can do besides just disabling the loading screen.
