The complete uncut output at the defaul loglevel is uninteresting.
The above is excerpted from loglevel trace, which gives nearly 1 GB of output
and is probably not helpful here in the entirety.
A lightly edited version and prematurely truncated version of the trace output

Perhaps recompose them in a better way.
Perhaps do some kind of blend or transition across the glitch rather than a
frame hold.
But I figured I'd worry about those after I got the baseline fix working.
Thanks.
And thanks for any suggestions how to do this better.
