skinparam shadowing fills in partitions and similar spaces dark grey

Question

Enabling shadowing with the new default skin can cause unexpected regions to be filled in with shadow.

This planuml snippet:

@startuml
skinparam shadowing true
(X)
partition "Graceful Cleanup " {
  :Close sockets;
  :Do other things;
  :Log shutdown;
}
end
@enduml

Causes the entire partition "Graceful Cleanup" as well as the entire end symbol (circle with X in it) to be filled in dark grey.

Hello W.,

There are some issues (only for PNG output), from:

A possible workaround is to add some style directive, as:

@startuml
<style>
partition {
  BackgroundColor white
}
end {
  BackgroundColor white
}
</style>
skinparam shadowing true
(X)
partition "Graceful Cleanup " {
  :Close sockets;
  :Do other things;
  :Log shutdown;
}
end
@enduml

And see the expected result:

If that can help,
I will check also to propose a Pull Request to PlantUML team, for that.
Regards.
