[Bf-committers] Problem with Lens distortion update

[Knapp]

I don't know the answer to your question but I was working with these two
parts of Blender. One thing that I learned is that they are completely
separate because the compositor takes its time to do the math right and
make a perfect image but the movie editor is programmed to update in real
time thus they take shortcuts to make it say super fast. Perhaps this will
give you clues as where to find it?
