Looks like an overheating GPU to me. |

Do you have accelerated graphics on for those panels? |

I'll bet if you turn it off the problem will disappear. |

The graphics card failed here on my Mac a year or two ago, and rather |
| 21 |
than pay £200 for an Apple-branded replacement, I found a regular PC |
| 22 |
graphics card on which a hacked firmware could be flashed. I have to |
| 23 |
under-clock it a little, and if I'm not careful I get a very similar |
| 24 |
effect to that in your pictures, but all over the screen. |

If you're able to boot to Windows it might be worth playing an FPS - |
| 27 |
if it crashes with graphical glitches then you may be able to get the |
| 28 |
card (or m/board?) replaced under warranty. |
