Description Eric Towns 2011-04-25 19:22:34 UTC 
Description of problem:
Rounded corners in CSS cause bleed-through of background images in Firefox browser window.  

This problem occurs in the Customer Portal home page - we narrowed it down to the following bit of CSS code - if you turn it off, the problem goes away:
-moz-border-radius-topleft:6px;
-moz-border-radius-topright:6px;

Steps to Reproduce:
1. navigate to access.redhat.com (Firefox, RHEL5, on a T61 laptop)
(see attached images)
  
Actual results:
bleed-through of background images

Expected results:
no bleed through (compare to Fx on a different machine type or another OS. 



Additional info:
The portal team is fixing this by making the image corners square in mozilla browsers, so after the next portal release the steps to repro won't apply.

I'm not certain which component this should be assigned to - please re-route appropriately.

Do you still see this bug? We updated the package with some fixes for that.
Comment 6 Eric Towns 2012-07-26 16:51:18 UTC 
Martin,

I don't recall seeing this issue for many, many months.  In that time, the test content has changed significantly, and I no longer have the old hardware/OS/browsers handy to test with.  I'm going to close this, and will clone or re-open if I find a reproducer with my current configs.  Thanks!
