The only thing I can think of is that your code is being called
when view is already focused, in which case the with-focused-view
in the loop is a nop, and any drawing that happens after the loop
exits will still see the last value of some-other-region
as the clip region. Try changing it to:
(loop for obj in list-of-objects
do (with-focused-view view
If that doesn't work, and you can distill your code into a
small, self contained, example that illustrates the problem,
I'll look at it.
