That works very well, thanks! From my own 'naive' analysis, I had been wondering
if a smaller block size would help, but I never tried it. (For my tests, I
forgot to mention that my media object occupies about 50% of the screen space--
unlike the OP's small object that is probably 'enclosed' by a single render
block.) Your suggestion works in both cases, of course.

A smaller render-block size has another great advantage: The scene renders
faster.
Here is my example (using scattering media):

block size of 64 pixels: 2 mins 16 sec
block size of 8 pixels:  1 min 10 sec

That's a definite improvement! And my machine's processor seems to run less hot,
based on the cooling-fan speed.
