Buttons disappear and do not render

[Jerry P]

Binary package hint: firefox-3.0

The buttons and entry boxes on this launchpad page and any website with buttons and entry boxes are not visible as I scroll up and down on this page using Firefox. If I mouse over the buttons they then become visible. I don't have this problem with the other browsers and I have pretty well given up on Firefox and now use Opera almost always. I know that Firefox seems to be the default approved Linux browser but I think this needs to be evaluated again as Firefox for Linux no longer works as well as Opera or Konqueror as sometimes It also will freeze up.
