Crash on Replay

[darksylinc]

Description

Capturing a Godot project from latest master branch on Linux succeeds and has no validation errors; but replay crashes RenderDoc.

Steps to reproduce

1. Load the capture I am attaching
2. Crashes with the following callstack:

1  fill_sampler_stage          lvp_execute.c    1116 0x7fff9126fae8

Repro:
RenderDoc.zip

If you think you need access to the original app to capture it, I can arrange that (it takes me time to setup the demo)

Environment

• RenderDoc version: 1.30 (also master c4e3f96)
• Operating System: Xubuntu 20.04 LTS
• Graphics API: Vulkan

Driver: RADV
AMD Radeon RX 6800 XT (navi21, LLVM 15.0.7, DRM 3.46, 5.18.11+)
Mesa 23.2.1 refresh - kisak-mesa PPA

App passes validation and presents correctly.

AHHHH FOR THE LOVE OF GOD.

By my own mistake the system picked up lavapipe (non-conformant SW Vulkan implementation) instead of my HW.

The problem goes away when using real Vulkan HW.

Closing this ticket.
