Cell background colours are broken in tabu. When I change
the MWE to use the tabular environment…

 \begin{tabular}{|l|l|l|}

… things look as expected. Building on stretch (don’t have

Large actual use case:

Also exists on latest sid. (I’ve initially reported against
the older version on the system I noticed it on so you might
have it easier to track down the change at fault, but rete‐
