BrightField particle has wrong position

[litpuvn]

Re-run the tracking particle using cnn, and i found that the particle didn't display correctly. The position looks like at (15, 15). However, its real position is (32, 32). Get position method also returns (32, 32) as initial setting.

Running on Ubuntu 22, python 3.9.12

mie_particle = dt.MieSphere(                                         
    refractive_index=1.58,
    radius=0.5e-6,
    position=(32, 32),
    position_unit='pixel',
)

IMAGE_SIZE = 64

brightfield_microscope = dt.Brightfield(
    NA=0.9,                
    resolution=1e-6,     
    magnification=10,
    wavelength=680e-9,
    output_region=(0, 0, IMAGE_SIZE, IMAGE_SIZE),
    padding=(32, 32, 32, 32),
    upscale=2
)

imaged_particle = brightfield_microscope(mie_particle)

output_image = imaged_particle.update().resolve()

plt.imshow(np.squeeze(output_image), cmap='gray')
plt.show()

You can remove upscale=2 and the particle is positioned correctly again. There seems to be a bug with upscale. I'll look into it.
