I have access to the Ubuntu machine again now.  The symptom I see now the same as on Fedora -- I can scroll
the source window, when when I focus on the command window, I start seeing all the badness.  I don't think
I focused on the command window earlier when I first reported it, maybe there's some other way to trigger
it, but can't say for sure.  So it is looking like this isn't OS specific afterall.

Sorry for the spotty reporting.  Hopefully the reproducer helps identifying the issue.
