Description of problem:

I think this might be an Xserver problem or GUI toolkit problem, but the only
repeatable place I've observed it is during Anaconda installer runs.  Perhaps
someone more knowledgeable about anaconda would change the component assignment
for this bug report.

When scrolling the package list in an install to select optional packages, the
items are sometimes garbled and alternately replacing/repeating one entry
instead of showing the proper list. I've noticed this particularly in the list
of graphical tools.

Version-Release number of selected component (if applicable):

Stock Fedora 8 installer using PXE or diskboot.img boot kernel and FTP-based
network install.

How reproducible:

Always, observed for Intel, Nvidia, ATI Radeon, VMware, and VNC based graphical
installs.

Steps to Reproduce:
1. Run a fresh install using the standard media.
2. Enable detailed package selection during install.
3. Go to graphical tools packages and scroll up and down in first dozen or two rows.
  
Actual results:

Entries are garbled and it isn't possible to be sure which item is actually
being selected when clicking on a checkbox. Scrolling back and forth or clicking
may or may not refresh the row and change the displayed text.

Expected results:

Rock solid scrolling with no repeated or garbled row displays.
