Hookshot version

v2.0.13

What kind of problem

Graphics (missing, black or wrong-coloured things, lighting, flicker)

What happened

Hookshot version

v2.0.13 (also on v2.0.12). It did not happen on v2.0.11, same PC, same save.

What kind of problem

Graphics (wrong-coloured things)

What happened

The glowing crystals on the walls and ceiling of Dodongo's Cavern render as blocky, oversaturated rainbow patches (red, green, blue, magenta, cyan) with a strong glow, and some floor areas glow green/blue. It appears immediately on entering, always in the same places, every time. It does not build up over play time and save/reload doesn't clear it, so it doesn't look like #993. Possibly related to the AMD rendering tracker #1006.

Where in the game

Dodongo's Cavern, 1F (entrance area)

How often

Every time

Graphics card and driver version

AMD Radeon RX 6700 XT (12 GB), Adrenalin [26.10.x] (log: Vulkan driver 0x800161). Same result on 26.8 before updating.

CPU, RAM and operating system

Ryzen 5 5600X, 32 GB RAM, Windows [10/11]

Changes from the defaults

Fullscreen 1920x1080, Windows HDR off. VRAM is far from full (about 1–7 of 11 GB used).

Tried in hookshot_env.txt, one at a time, confirmed in the log that each applied. None changed anything:

RX_VK_ASTC_RGBA8=1 (big textures load as RGBA8, the "kept as BC3" line disappears; still rainbow)
RX_VK_DESC_REUSE_DGEN=0
RX_VK_UPLOAD_BUDGET_MS=1000
RX_VK_SHADOW_PCF=0
RX_VK_NO_PROGRAM_CACHE=1
RX_VK_NOOPT=1
Frame generation off (normally 3x)

Relevant log lines

Every time I enter the cavern, with or without any of the switches above, and on both driver versions:

vk: BC image 1536x1460x1 (vk 143) as a raw colour attachment: the driver says -11
vk: BC image 3072x2920x1 (vk 141) as a raw colour attachment: the driver says -11
vk: BC image 1120x1536x1 (vk 143) as a raw colour attachment: the driver says -11
vk: BC image 2240x3072x1 (vk 141) as a raw colour attachment: the driver says -11

Repeated many times while in the cavern:

vk: storage buffer NOT bound (reads zeros): program da7a7ab28b8e73d9 stage 1 c5+0 addr 0x4180000000000200 size 0x20

Also each time:

vk: a draw (program 3e753d8ad4012b7b) samples the colour target it writes (130x130, read undefined where it writes)

Likely cause

-11 is VK_ERROR_FORMAT_NOT_SUPPORTED. It looks like the GPU-written BC6H (vk 143) and BC5 (vk 141) textures can't be used as raw colour attachments on RDNA2 under AMD's Windows driver, so they are never written and keep garbage memory. Garbage BC6H (HDR) data would explain the blocky, oversaturated rainbow glow on exactly the emissive crystals. v2.0.8 fixed BC storage views on AMD's Windows driver (#1052), so this may be a regression of that path in v2.0.12.

Other software hooked into the game

hookshot_log.txt

Attached (latest run, after a driver update and a restart).

Screenshots or video

Attached (two screenshots, Dodongo's Cavern 1F).

Did not bother updating to 2.0.14 Since it did not include any changes that could fix this

Hi! I have the same GPU and made some changes to fix a few issues (I believe these fixes will be included in version 2.0.15). Could you check my fork to see if the same bug still occurs?

Thanks for the report. Reports of the same problem are now collected in #1006, which lists this one with your details and links back here, so one fix closes them together and the open list stays readable. Follow #1006 for the fix, and add new details there (or here). If this turns out to be a separate problem it will be reopened.
