Not exactly.  You see, some programs (like less and vi) actually use a 
secondary display buffer.  If you use the arrow keys, you can tell less 
(or vi) to change what portion of the file they display in that 
one-screenfull-tall buffer.  However, if you use the scroll bar, you 
then see the primary buffer contents.

That is, less/vim will always ONLY control ONE screenful of data.  If 
you scroll OUT of that screenful, then you see .... bash?

This behavior is what allows bash(?) to restore the previous "bash" 
display after you exit vi or less.

Summary: not a bug.

I use rxvt exclusively, in both X and native modes.  I've never seen this.
