The error

Title: AMD Radeon RX 580 (Polaris, 4 GB): Vulkan back end boots and reaches
gameplay, but the world renders as colour noise / solid blue

Environment
- Windows 11 (10.0.22631), Radeon RX 580 Series 4 GB, Intel Core i7 7th gen, 16 GB DDR4
- Game built with HookshotBuilder, default back end (hookshot_vk.dll)
- Log: "vk: Radeon RX 580 Series, Vulkan 1.3, driver 0x800117; mesh shaders no,
  host memory import yes, pipeline libraries no"

What works
- Boot, title screen, intro movie (only after installing Microsoft's "AV1 Video
  Extension"; without it the movies are black with sound), leaving Link's house, saving.
- A menu-like scene at a steady 60 fps (248 draws, 0 skipped).

What does not
1. Colours: 3D scenes are drawn as high-contrast colour noise (terrain) with a flat
   cyan/white sky, often just the solid blue clear colour plus HUD. Link's model in
   the equipment menu is almost black (rim light only). UI icons look correct.
2. RX_VK_ASTC_CPU=1 changes nothing, so it is not the GPU ASTC decode.
3. In gameplay (~700-2100 draws per frame) about 50-70 draws per frame are skipped at
   vk_draw.cpp:2692 ("a draw without a program", stage keys 6 and 7, which I assume
   are task/mesh). Also 12 dispatches per frame are skipped at vk_draw.cpp:3429, already
   at the title screen; the comment there says skipped dispatches leave garbage in the
   sky/terrain. The log also has: "program 0000000000000000 does not translate:
   dispatch replaced by linear upscale 1920x1080 -> 2560x1440".
4. About 560,000 DrawMeshTasksIndirect calls over the session.
5. vk_shader.cpp builds the recompiler profile with max_subgroup_size = 32 and
   warp_size_potentially_larger_than_guest = false without querying the device. GCN
   runs wave64, so shaders using vote/ballot/shuffle may misbehave. Could the profile
   be filled from VkPhysicalDeviceSubgroupProperties?
6. Performance (7-27 fps) is CPU-bound: in one frame with 1638 draws the GPU takes
   ~15 ms, but replay takes draw 156 ms + descriptors 118 ms + texture lookups 61 ms +
   submit 79 ms. VRAM is saturated ("3433 MB used of 3433 MB allowed") and textures
   are retired constantly.
7. Pressing Start after leaving the house gives a black window with menu music for
   1-2 minutes.

Questions: is AMD (wave64, no mesh shaders) supported or planned? Would a compute
fallback for mesh/task programs be considered? Which extra logs would help?

I'm on the newest release, or it still fails on it.

Thanks, that's right: the movies are AV1, and on Windows the game decodes AV1 through Windows itself, which needs Microsoft's free 'AV1 Video Extension' (most PCs have it, some don't). The next release says so the first time it happens and offers to open the extension's Store page, instead of leaving the movies black. Bundling an AV1 decoder of our own is on the list.

The new release is out: https://github.com/NotRexed/Hookshot/releases/tag/no-visual-studio. Please rebuild with it and tell me here whether it's fixed for you (attach hookshot_log.txt if not).

Tracked in #1001, follow there. That issue collects every report of GPUs without mesh shaders, and this one is linked from it with its GPU, version and log details. v2.0.6 brings back the fallback for GPUs without mesh shaders (PR #779). It is untested on these cards, so a v2.0.6 result from you would help. If it still happens on v2.0.6 (https://github.com/NotRexed/Hookshot/releases/tag/v2.0.6; Update next to Play in the launcher), please add a comment there with your hookshot_log.txt.
