[SOLVED] Segfault when running some programs

bababoey · 2025-07-26 14:32:46

Everything works fine yesterday then this happens.

Selected WSI platform: wayland
[obs-vkcapture] Init Vulkan 1.5.2 (64bit)
Segmentation fault         (core dumped) vkcube

Web browsers, discord, steam, and flatpaks works fine but mpv, vlc, majority of my steam library, and lutris does not even launch.
I was able to launch project zomboid on steam (opengl) so I thought it has something to do with my vulkan drivers but I am also able to play games on my emulators using vulkan renderer (flatpak).

What, exactly, is liblsfg-vk.so? It doesn't appear to exist in the repos.

V1del · 2025-07-26 14:59:45

Probably https://aur.archlinux.org/packages/lsfg-vk-git you'll want to check whether rebuilding that fixes things or remove it.

bababoey · 2025-07-26 15:02:29

Removing the package fixes it, TYSM!!!

V1del · 2025-07-26 15:11:18

If you consider that a solution and don't want to investigate into why it breaks/potentially report upstream, please mark as [SOLVED] by editing the title in your first post.

FWIW out of own curiousity, it seems recent commits changed the way this should get configured and you're likely dying in the config parser somewhere, see https://github.com/PancakeTAS/lsfg-vk/w … E2%80%90vk -- from context https://github.com/PancakeTAS/lsfg-vk/pull/135 might fix this.

Might also be because I have an older version of Lossless Scaling installed in Steam but I never thought this package was the problem since it's just sitting on my system and I was not actively using it.
Nevertheless, thanks for the help.
