Display problem - is this a bug?

[Barry Levine]

I've seen an issue with scrolling fields where sliding the "thumb" back 
up reveals the previously hidden lines of lext but the text is broken 
up as if it was printed with a clogged inkjet printer. I have a screen 
shot and will eMail to anyone if asked. However, you can reproduce it 
by displaying the Transcript Help window, selecting "Filter" from the 
popup, typing a few letters (try "ba"), clicking below the thumb to 
scroll the field down, and then dragging the thumb back up. You'll see 
that the text is goofy looking. The larger the thumb is (less lines of 
text), the more pronounced the problem is.

I can't believe I'm the first to see it. Has this been bugzilla'd?
