View PNG file problem on Qt 4.8 for QNX

Hello.
At loading *.png files in the program, I receive not correctly the image, the transparency doesn’t work:
On windows 7 [imglink.ru]
On qnx 6.5 [imglink.ru]

I use qt 4.8 rc1 in qnx 6.5.
Library collected with following parameters:
./configure-release-opensource-xplatform unsupported/qws/qnx-i386-g-embedded x86-no-gfx-linuxfb-no-mouse-linuxtp-no-kbd-tty-no-qt3support-qt-mouse-qnx-qt-kbd-qnx-qt-gfx-qnx-depths 16,24,32, generic-no-exceptions-no-qt3support-qt-libpng-qt-libmng-qt-libjpeg-no-phonon

The driver qnx works in a mode argb8888.
