after downloading a picture I can see vertical lines in the picture. after refreshing or minimize the browser and maximizing it again the lines will not be shown. 
Seems the issue can be reproduced when the downloading is interrupted or delayed.

Note: can send you a screenshot with the lines if needed!

Reproducible: Sometimes

Steps to Reproduce:
1. open browser
2. go to URL http://www.macenstein.com/images/2008/mg_2008/2008_11/desktop_mcotm_08_11b.jpg
3. during downloading the picture is partly shown but it stucks for a short moment.
Actual Results:  
 after the download continues, there is a white line shown 

Expected Results:  
no lines in the picture
