Is there anything we can do about it?

Please help - why does SVP not work with rusticl, does not see opencl/GPU?

There are no errors, but the Settings→GPU acceleration→No acceleration.

At the same time, it worked with rocm-opencl-runtime-5.5.1, but it no longer worked with rock-opencl-runtime-5.7.1-r1. Moreover, since 5.7.1-r1, GPU acceleration was detected correctly, only there was no FPS increase, but there were no errors in the logs. 5.5.1 I didn't want to, because it's the only one that requires llvm-16.

AMD Radeon RX 6700 XT, Gentoo x86_64, media-libs/mesa-24.1.0-r1, kernel 6.6.30, GPU driver is free, SVP is the latest release.

Installed:
dev-libs/opencl-icd-loader-2023.12.14
media-libs/vulkan-loader-1.3.280.0
dev-util/spirv-headers-1.3.280.0
