Dear list,
with the (almost minimal) example below, I hoped that the frame would
be recalculated at every page. But it is not (they all look the same
in my output pdf). How can I force the frame to be redrawn at every
page?
Btw, If I change the uniqueMPgraphic to useMPgraphic (everywhere) my
file does not compile anymore. I get some lua error.

That's not how uniqueMPgraphics work.

Thank you Marco for giving a better example.
I thought that uniqueMPgraphic meant it was redrawn everytime while
useMPgraphic meant it was done once and then gave the same result
everytime used. I probably misunderstood something in the MetaFun
manual.
In any case: Is there a way to get different frames for every page in
a random way?

Using \startuseMPgraphic is the correct way, since you want the
graphic to be recalculated every time. I have no clue why this
fails at the moment. It works fine in older versions, so I assume
it's a bug.

Ok, thank you Marco.
Hans, is this a bug? Has something changed?

it's reused *when possible* depending on some characteristics (like
width and height)

Hi Mikael,
your original example works for me with a current beta if you
replace uniqueMPgraphic with useMPgraphic.
