Icon and another picture looks wrong

Hi
I'm running application on directfb ( hard is Sigma smp8635 , directfb version is 1.0.0)
App run but Icon picture looks wrong.
When I run " ./app -qws directfb -decoration windows " right side buttons ( i.e : close button)
color is Red. I run QtWebview to see "www.google.co.jp" , and that icon (png file) color almost fill by pink color.
And I use QListView to see local directory , It color almost fill by pink color like google icon .
I use QPixmap to see local file , and it seems OK. ( this png file color is few)
Does anyone has same experience , or solution to solve this problem ?

Thanks.
