macbook pro graphics glitches?

Hello,

As some of you may know, about 2-3 weeks ago I got a macbook pro 15". It works fairly well.

But I have come to notice a few fairly annoying graphics problems.

I put together a slide show of a few unity demos and a few screens from minecraft.

In all of them you can see some sort of black lines or glitches.

Here is my system info:

Code (csharp):

1.   Chipset Model:    AMD Radeon HD 6490M
2.   Type: GPU
3.   Bus:  PCIe
4.   PCIe Lane Width:  x8
5.   VRAM (Total): 256 MB
6.   Vendor:   ATI (0x1002)
7.   Device ID:    0x6760
8.   Revision ID:  0x0000
9.   ROM Revision: 113-C0170H-521
10.   gMux Version: 1.9.23
11.   EFI Driver Version:   01.00.521
12.   Displays:
13. Color LCD:
14.   Resolution:   1440 x 900

17.   Mirror:   Off
18.   Online:   Yes

Now I was wondering if anyone on these forums had a similar computer. And was experiencing similar problems.

If anyone here has a solution, it would be most helpful to know.

Thanks.
