Comment 35 for bug 243682

Now that bug 243682 is separated, I think this description needs some cleanup to be more specific to just the red/white lines corruption and not talk about the progress bar issue, as that is likely to confuse people finding/following this bug report. The startup video probably belongs in the other report.

I also wanted to confirm that both of these issues affect me, seemingly random which one, at startup; shutdowns have not been affected as far as I have noticed, though my experiments were far from scientific.
