   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 🙏
