Background color leaks to next row when scrolling

[Lachezar Dobrev]

Binary package hint: gnome-terminal

The background (and possibly foreground) colour leaks to the next row when the output forces the terminal to scroll down while wrapping the coloured text.

Reproduction is relatively easy:
1. Open terminal.
2. Create a link to a missing file with a long path, so that it needs to wrap.
  ln -s /path/to/some/very/long/and/definitely/missing/file sample
3. List the file (long format with color)
  ls -ln sample
4. Continue listing until the terminal fills up, and starts wrapping and scrolling at the same time.
5. Observe the new lines background colour.

I can't get the color scheme you're using, and bug doesn't re-produce on the scheme I have.

Brian, it seems that the amount of text wrapped has something to do with this behaviour's exhibition.
Please try with shorter links, that would wrap just a few characters.
See the attached image. However if I follow the reproduction path the bug does not show.
Please try again with a shorter link. I am using 'Standard Colors' and 'Rxvt' colour theme.

Thank you for taking the time to report this bug and helping to make Ubuntu better. The issue that you reported is one that should be reproducible with the live environment of the Desktop CD of the development release - Oneiric Ocelot. It would help us greatly if you could test with it so we can work on getting it fixed in the next release of Ubuntu. You can find out more about the development release at http://www.ubuntu.com/testing/ . Thanks again and we appreciate your help.

It was a b*tch to get the ocelot running on any of my machines.

However I have successfully replicated the issue in the Alpha 3 version using a Live-USB.
1. Create a Live USB (not CD)
2. Boot from it.
3. Try without installing
4. Open terminal
5. Type: ls -l /

Since the Live-USB does not have a vmlinuz and initrd.img in /boot the symbolic links in the root are broken, and have a dark background.
The first try shows colour bleeding on the /vmlinuz symbolic link, subsequent ls -l in the same terminal show colour bleeding on the initrd.img link too.
