Color Streaking & Shifting on T520 HD screen

[baertracks]

Has anyone had problems with color streaking on the the T520 HD screen?
Here is what I am seeing..

It's actually worse than that it that all the colors seem to have shifted to a sort of psychedelic blues and pinks.
Rebooting fixes the problem, but I'm wondering if I should be concerned.

A bit later...
Actually, this time rebooting did not fix the problem (either a restart or a cold reboot).
Moving the screen back and forth seems to affect the degree of the problem.
I called IBM and they think that it may be a bad cable and/or screen.
They will be sending a technician with parts to look at it on Wednesday.
