I believe this is a duplicate of bug#67791, so I'm merging them (and
reopening 67791).  FTR, the bug is in pixel-fill-region, not in the
above commit (which just exposed the bug in pixel-fill-region).

The discussion of bug#67791 includes a workaround and my suggestion
for a better solution.  Can you try those and see if they solve this
problem?
