Geekbench 5 "Feature Matching" benchmark error..

Hi,
just testing CLon12 perf/correctness under Geekbench 5..
CLon12 package is Win Store version 1.2105.3.0..

all tests, except the shown in title, seem to run correctly..
run with: geekbench5 --compute OpenCL --compute-platform-id 2 --compute-device-id 0
err shown is:

Running Feature Matching
[0512/065245:ERROR:compute_workload.cpp(111)] workload 311 failed validation

other thing, is performance is an order of magnitude slower than native OpenCL at least on Nvidia..

Geekbench 5.2.3 Tryout : https://www.geekbench.com/

Geekbench 5 is in tryout mode.

Geekbench 5 requires an active Internet connection when in tryout mode, and
automatically uploads test results to the Geekbench Browser. Other features
are unavailable in tryout mode.

Buy a Geekbench 5 license to enable offline use and remove the limitations of
tryout mode.

Reproduce the failure with Geekbench 5 using geekbench5 --compute OpenCL --compute-platform-id 2 --compute-device-id 0, focusing on the Feature Matching workload and the reported workload 311 failed validation error. Compare the linked OpenCLOn12 and native OpenCL results to investigate the reported performance gap; done means Feature Matching passes validation and the performance discrepancy is characterized or resolved.
