I'm having trouble reproducing this with various backends and image sizes.
af.info()
af.set_backend('opencl')
img = af.randu(3,3)
max_val, max_idx = af.imax(img)
max_valf, max_idxf = af.imax(af.flat(img))
print(img)
print(max_val)
print(max_idx)
print(max_valf)
print(max_idxf)

This is with the latest wheels. Can you provide more info what system/gpu/release/backend/OS/driver version/python version you're seeing the wrong behavior? Sample data or a minimal reproducible code snippet would be appreciated as well 🙏
Let me know if this is helped arrayfire version: 3.6.20181017
[[0.07369253, 0.06271768, 0.05245196], [0.08713178, 0.07496584, 0.06345784], [0.10122371, 0.08787344, 0.07517199]]
max_val, max_idx = af.imax(img)
running this function seems to have wrong behavior and finds wrong max value for an image with pixels in range [0,1].
When running
max_val, max_idx = af.imax(af.flat(img))
the correct max value is found.
