it's also the first time I notice it. maybe it has something to do that
these scalars come from different templates (structs).

in this case it surely doesn't have anything to do with z-order, as anyway
scalars are redrawn (and go to the front) when something in them is edited.
sending the background message (as well as some others I prepared) only
corrects the problem, because the patch rewrites a value from the scalars,
so that they come to the front - it's not an "automatic" pd reaction.

it would surely help, but I'm not sure when I would have the time for it. I
started doing one, but then it didn't work immediately, so I put this one
