Suddenly started to fail today, after updates I guess, with the same message as in #5943, ValveSoftware/Dota-2-Vulkan#371

Hello @sequencerr, you haven't provided any context as to what exactly is failing, but you've implied that whatever it is, it's Vulkan related.

From your steam-runtime-system-info-1737740269.txt:

      "graphics-details" : {
        "x11/vulkan" : {
          "renderer" : null,
          "version" : null,
          "issues" : [
            "cannot-load",
            "cannot-draw"
          ],
          "exit-status" : -1,
          "terminating-signal" : 11,
          "terminating-signal-name" : "Segmentation fault",
          "devices" : [
          ]

Vulkan is broken in general in the environment you're running Steam. This is a packaging issue outside of Steam.

If you're using the NVIDIA proprietary driver and recently changed the installed driver version, you may need to reboot and/or run an update cycle on Flatpak for it to pick up on the system changes. If that doesn't help, then follow up with your distro's community.

Closing as not a Steam client issue.
