Thanks. This is definitely a bug, but very different from my understanding of what was reported (which is why one should always tell someone how to reproduce a problem in a bug report). It is because the PushFormat is done regardless of whether it is a new viewer or just the same viewer being set again.
Absolutely needs to be fixed. I don't like the idea of cluttering up the object landscape of PETSc even more by adding new objects such as "viewer plus format" as was suggested. I need to think about a way to fix this that results in less cluttered code, nor more cluttered code.
