Hi Wayne,
The misaligments can be fixed by adding a few control points, as per 6.41:

PTGui 13 will be able to handle this better, without manual control
points, but the Qoocam Ultra was not yet supported in the current beta.
But regarding the colors, I haven't seen this in the test DNGs I have
from this camera. Or was it just a badly exposed image? If not, could
you share your image?
