Strange display problem

[alexis0070]

Hello, I am using macbook air (haswell) i5/8/128 and I am experiencing a strange problem. When the mac wakes up by opening the screen, it appears (for a second) something really weird! it is something like this...

Nothing too annoying, but I am nervous about the graphics!
Thanks and sorry for my English!

That's not normal, even if just for a second. I'd bring it back in the store for repair/replacement. It could gradually get worse over time. Better to nip it in the bud now.

I did a reboot and the problem solved. I love that kind of simple solutions. Thanks for the reply!
