Refresh problem in the winpdb UI, scrolling down creates grey lines

[GoogleCodeExporter]

What steps will reproduce the problem?
1. open winpdb
2. scroll down in the source window (the other windows seem ok)
3. you'll see a solid grey bar going across every third line

What is the expected output? What do you see instead?

Shouldn't see solid grey bars

What version of the product are you using? On what operating system?

1.4.8 ; Ubuntu 11.04 x86_64

Please provide any additional information below.

The lines go away when I do a resize for the source pane, but come back again 
as soon as I scroll down again.  Weirdly enough, scroll UP does NOT cause 
problems.

also tried getting to lower text by way of the keyboard down key, this issue 
doesn't manifest with that approach.  

It may or may not be helpful to note that python-wxversion is 2.8.11 , so it's 
not exactly the 2.6 that winpdb is looking for, but it doesn't trigger any 
complaints because the current winpdb code is happy with "2.6 or higher" (which 
is maybe fine).

reproduced this defect with the attached (very very simple) code.  This 
strongly implies that perhaps it's a bug in python-wxversion 2.8.11 ... I'm 
going to try chasing that next.
