I did that, and found that if I installed libgnomeprintui2.2-0:

  $ sudo apt-get install libgnomeprintui2.2-0

the printing dialogue changed the next time I ran tv.  It looks like
the default built-in print dialogue is broken, and the replacement
used when libgnomeprintui2.2-0 is installed (verified by checking
/proc/$pid/maps) is working correctly.  If you remove

  libgnomecups1.0-1 libgnomeprint2.2-0 libgnomeprint2.2-data
  libgnomeprintui2.2-0 libgnomeprintui2.2-common

From your system temporarily, you should see the broken dialogue.

As a short term workaround, I would recommend a direct Depends on
libgnomeprintui2.2-0.  Depending on where the other print dialogue is
coming from, this might be more appropriate as a wxWidgets dependency
if it's something the underlying wxWidgets is using.  If the print
dialogue is a direct part of treeviewx, putting the Depends in
treeviewx would be more appropriate.

They look like different bugs.  The display bug looks partly like it's
not handling expose events correctly (if you "wipe" another window in
front of treeview to force an expose, it corrupts the diplay badly).
On another system, the display is unreadable (everything is sqashed
into the left side of the screen, whatever the window size).  The
visual effects look like it's probably a similar cause.  Is tv
calculating different display sizes in different functions?
