Hookshot version

v2.0.14

What kind of problem

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

What happened

System
Hookshot v2.0.14 (source 3a9998c3), Linux build
Ubuntu 24.04, kernel 7.0.0-34-generic
AMD Ryzen laptop, Radeon 780M iGPU (RADV PHOENIX), Mesa 25.2.8
30 GB RAM
What happens
In-game the image flickers constantly and large areas render pure white, as if exposure is blown out (photo attached, Kokiri Forest). Mostly 20–45 fps.

Turning Frame generation off (it was 2x) helped with ghosting/shimmer: the log showed FSR 3.1 made only 0–64 of every 600 interpolated frames ("without its inputs"), the rest came from the fallback. The white/flicker issue stays.

What the log shows
Auto-exposure / luminance chain samples the target it writes. Program 3e753d8ad4012b7b at 65x65 → 32 → 16 → 8 → 4 → 2 → 1: vk: a draw (program 3e753d8ad4012b7b) samples the colour target it writes (32x32, read undefined where it writes) My guess: the average luminance comes out as garbage, so exposure is wrong and changes every frame.
storage buffer NOT bound (reads zeros): program da7a7ab28b8e73d9 stage 1 c5+0, about 40 times per session.
texture slot ...: no image for it, 60–130 times per session (various 341–3072 px textures).
Things I tried
RX_VK_OOT_VISUAL=1 (in hookshot_env.txt): the log shows it patched ~100 exposure programs and the fog program, but the 3e753d8ad4012b7b feedback-loop warnings are still there. Result in game: (fill in: better / same / worse)
Graphics menu: Handheld profile On, Render resolution 50%, Frame generation Off.
Separate: freeze on start without /dev/udmabuf (kernel bug, FYI)
At first the game froze at the first submit. /dev/udmabuf is root:kvm 660 on Ubuntu, so Hookshot fell back to host-pointer imports, and the amdgpu driver on kernel 7.0 oopsed (NULL deref in amdgpu_hmm_invalidate_gfx via amdgpu_gem_userptr_ioctl, see kernel_oops.txt). Fixed with:

/etc/udev/rules.d/70-udmabuf.rules: KERNEL=="udmabuf", SUBSYSTEM=="misc", TAG+="uaccess"
/etc/modprobe.d/udmabuf.conf: options udmabuf size_limit_mb=16384
It might be worth suggesting this in the log message or docs for AMD users on Linux.

I'm on the newest release, or the problem is still there on it.
I searched the open issues for this problem.
I'm not attaching game files, keys, hookshot.exe, the .bin caches or saves.

### Hookshot version v2.0.14 ### What kind of problem Graphics (missing, black or wrong-coloured things, lighting, flicker) ### What happened System Hookshot v2.0.14 (source 3a9998c3), Linux build Ubuntu 24.04, kernel 7.0.0-34-generic AMD Ryzen laptop, Radeon 780M iGPU (RADV PHOENIX), Mesa 25.2.8 30 GB RAM What happens In-game the image flickers constantly and large areas render pure white, as if exposure is blown out (photo attached, Kokiri Forest). Mostly 20–45 fps. Turning Frame generation off (it was 2x) helped with ghosting/shimmer: the log showed FSR 3.1 made only 0–64 of every 600 interpolated frames ("without its inputs"), the rest came from the fallback. The white/flicker issue stays. What the log shows Auto-exposure / luminance chain samples the target it writes. Program 3e753d8ad4012b7b at 65x65 → 32 → 16 → 8 → 4 → 2 → 1: vk: a draw (program 3e753d8ad4012b7b) samples the colour target it writes (32x32, read undefined where it writes) My guess: the average luminance comes out as garbage, so exposure is wrong and changes every frame. storage buffer NOT bound (reads zeros): program da7a7ab28b8e73d9 stage 1 c5+0, about 40 times per session. texture slot ...: no image for it, 60–130 times per session (various 341–3072 px textures). Things I tried RX_VK_OOT_VISUAL=1 (in hookshot_env.txt): the log shows it patched ~100 exposure programs and the fog program, but the 3e753d8ad4012b7b feedback-loop warnings are still there. Result in game: (fill in: better / same / worse) Graphics menu: Handheld profile On, Render resolution 50%, Frame generation Off. Separate: freeze on start without /dev/udmabuf (kernel bug, FYI) At first the game froze at the first submit. /dev/udmabuf is root:kvm 660 on Ubuntu, so Hookshot fell back to host-pointer imports, and the amdgpu driver on kernel 7.0 oopsed (NULL deref in amdgpu_hmm_invalidate_gfx via amdgpu_gem_userptr_ioctl, see kernel_oops.txt). Fixed with: /etc/udev/rules.d/70-udmabuf.rules: KERNEL=="udmabuf", SUBSYSTEM=="misc", TAG+="uaccess" /etc/modprobe.d/udmabuf.conf: options udmabuf size_limit_mb=16384 It might be worth suggesting this in the log message or docs for AMD users on Linux. Attachments (hookshot-report.zip) 0_freeze_without_udmabuf.txt: log of the freeze 1_run_default_settings.txt: first working run 2_run_framegen_2x_render50.txt: frame gen 2x, render 50% 3_run_RX_VK_OOT_VISUAL_1.txt: with RX_VK_OOT_VISUAL=1 kernel_oops.txt, system_info.txt screenshot/photo of the white flicker ### Where in the game Walking out link house ### How often Every time ### Graphics card and driver version Radeon 780M iGPU (RADV PHOENIX), ### CPU, RAM and operating system 32GB RAM, AMD Ryzen 9 270, Linux ### Changes from the defaults Things I tried RX_VK_OOT_VISUAL=1 (in hookshot_env.txt): the log shows it patched ~100 exposure programs and the fog program, but the 3e753d8ad4012b7b feedback-loop warnings are still there. Result in game: (fill in: better / same / worse) Graphics menu: Handheld profile On, Render resolution 50%, Frame generation Off. ### Other software hooked into the game No, nothing hooked in ### hookshot_log.txt === hookshot_log.txt (excerpt: start of the run + distinct warnings;

Thanks for the report. Reports of the same problem are now collected in #997, which lists this one with your details and links back here, so one fix closes them together and the open list stays readable. Follow #997 for the fix, and add new details there (or here). If this turns out to be a separate problem it will be reopened.
