Crashes under Linux with Mesa Radeon driver when firing a gun :-(

[vitalif]

Hi, I'm not sure how exactly to debug this problem, but when I try to fire a gun, Minecraft 1.18.2 + Forge 40.1.51 + cgm 1.2.5 crashes with a segfault inside Mesa Radeon driver during some texture operation.

The same also happens with Intel integrated GPU and gunmod 1.2.6. With Intel it doesn't happen with 1.2.5, but with Radeon it does.

This is what I could get by installing debug symbols for Mesa:

Do you have any ideas?

Reinstalled from scratch, doesn't reproduce. It seems it's caused by some option...

[vitalif]

It's caused by one of optifine options ... :)

Hi, what was the optifine issue that was causing you this issue. im having the same problem you see

[vitalif]

Not sure. But on one PC I removed options.txt, optionsof.txt and optionsshaders.txt and it stopped crashing. On another PC I removed just optionsof.txt and it also stopped crashing. Funny thing is that I preserved the old copy of it and the new one is identical. :-/

[vitalif]

I suspect it's caused by reduced shader render resolution. At least when I returned optionsshaders.txt with 0.5x render resolution the game started to crash with Intel card again. Even though I run it without BSL shaders now
