Deformed image in Firefox while scrolling

[jippie]

Since upgrading from Kubuntu 12.10 to 13.04, scrolling in Firefox sometimes shows glitches. Most of the time too short lived to make a screendump, but I managed once. The glitching appears while scrolling but is intermittent.

1) The release of Ubuntu you are using, via 'lsb_release -rd' or System -> About Ubuntu
€ lsb_release -rd
Description: Ubuntu 13.04
Release: 13.04

2) The version of the package you are using, via 'apt-cache policy pkgname' or by checking in Software Center
€ apt-cache policy firefox
firefox:
  Installed: 20.0+build1-0ubuntu2
  Candidate: 20.0+build1-0ubuntu2
  Version table:
 *** 20.0+build1-0ubuntu2 0

        100 /var/lib/dpkg/status

The images as shown in my link are PNG's, but in the mean while I also noticed JPG's on other websites to glitch during scrolling. So far I only noticed it at the top of the screen.

BTW: I run Kubuntu 13.04, notice the K.

jippie,

We are sorry that we do not always have the capacity to review all reported bugs in a timely manner. You reported this bug over five years ago and there have been many changes in Ubuntu and Firefox since that time.

Do you still see this problem in the current release of Firefox? Please let us know if you do.

If we do not hear from you this bug report will expire in approximately 60 days time.

Thank you for helping make Ubuntu better.
