Hi Kirk,
Hopefully this will sort in the archives correctly. This isn't a true reply as the message isn't in my inbox anymore.

It seems the problem is your kernel loop is taking longer than you expected. Counting the cycles at the maximum cycle count shows the last branch happening at cycle 73. The loop branch crosses a page boundary so that's 4 cycles vs. 3. Doing this produces an extra scan when all your objects are on the same scan line.
Take care,
Dennis
