Screen issue or Software Bug?

see attached for a video.

Basically every reboot, at the OS X 10.9 login screen i get a distorted screen for several seconds, after about 5 seconds it stops and does not occur again when using the OS.

It is a repeatable bug as it will occur after every reboot. Anyone else experience this?

Never dropped, no liquid was ever near it.

Try resetting the SMC - may help and cannot hurt.

Otherwise, I would take it in for diagnosis (or ignore the issue as it only happens at startup).

Since i posted i have reset the SMC and erased and re-installed 10.9.2, i was able to re-produce the issue.

Looks like this will be a call to Apple

Did you try a PRAM reset?
