Hi

Purchased MBA 11 2014 few days ago, one thing i noticed is that, when i scroll web pages with bright background, dark fonts and images are getting much brighter.

I did google about it and from what i know this problem exist in all MBA?

You can see in while for example scrolling Youtube comments using touchpad.

If you visit for example this site http://www.wykop.pl/

and scroll down using 2 fingers, doesnt the font change color from dark blue to light blue ? (while scrolling only)
 
No. But if I look closely, it seems to "flicker" a little. I think that's just because the screen is being refreshed. But really, when I scroll it's because I want to move the page down. I don't read and scroll at the same time.

I see no flickering, color or font changes with Chrome, Firefox or Safari. I used both 2 finger scrolling on the trackpad and an external mouse, as well as the MBA standalone then with an external monitor.

Caveat: my MBA is a 13".
 
The text gets slightly lighter while scrolling. Lack of enough screen refresh.

My 2013 13" MBA does that, but I think your video makes it look a little worse than it looks in person. But yes... if you flip through a long web page quickly there is a bit of refresh lag with the text.

Funny thing is it it not noticeable at all with my MBA attached to the Thunderbolt Display in clamshell mode, so I suspect it is an more an issue with the MBA LCD refresh rate rather than a GPU power issue.

Yep its probably LCD problem, could be some problem with voltage according to this test

The text also get lighter when you for example move the browser window around.
 
Some sites seem to exaggerate the issue while others-- not so much. On forums like macrumors I don't really get the problem. However on particular sites like the one you linked, I do get it.

Maybe it's the way certain texts are rendered?
