I've compiled windowflags example for my embedded system. These problems occur when I run the example on the target ("here":http://qt.apidoc.info/5.1.1/qtwidgets/widgets-windowflags.html you can see how the example is supposed to look like):

titlebar is not present in the windows (there is no minimize, maximize and close buttons),

windows are layered one on top of another in a strange way (label from one window is covering part of another).

Here's the image on which it's shown how everything looks on the target.

Any help would be greatly appreciated!

I'm also facing the same issue. Is there any solution available for this ?
Further to this I see that Qt with DFB plugin is drawing on a fixed co-ordinates of 640x480. I don't get full-screen, though my frame buffer is 1280x720.
