Hi!
Heya!
If I remember correctly from the older days, I think this weird display is that the display turns on and shows the video frame buffer before it's memory is initialized for the current dispay settings.
Like Jerry said, no cause for concern. An update to drivers and/or kernel usually solves this. In some cases you could see the previous output (before the reboot)... albeigth with weird colors and all garbled up though.
ADD : Some "really" old ATI (before AMD) video cards were notorious to have random "green lines" when changing display resolutions. Also, a projector am using frequently displays some blue-ish image before the wanted output, so this can also be hardware related, but does not affect usage.
ADD2 : Some Monitors or TVs will be the culprits also, trying to display an incomplete video signal for a second or two. Most have a delay before displaying an image when detecting changes to the video output to prevent this and probably a "stress" on electronic components from what I understand.
