Could be its with transparent (PNGs) only, didn't test with more formats.

Steps to reproduce: (In video is more explicit) (in Cycles) Duplicate the array -> Apply Array -> Separte result by Loose Parts -> Create new materials for top parts -> Change PNG (embedded in file) -> Go to Lux , turn viewport render on and replicate changed PNGs -> Turn off and on viewport.
