Hmmmm, wouldn't have guessed it from your problem description
but I guess I should be happy it isn't an Amiga problem...  8-)

Yep.  Halfbrite is a mode in Denise that says to take the data from
the sixth bit plane and use it to control whether or not the outputs
from the color table are shifted to the left by one bit position.

None of the other chips have a clue that this is happening.  Agnus
is involved only to the extent that it's been told to fetch 6 bit
planes, but that could be either EHB or HAM...
