Layout in some examples is not good for small screen

Path Stroke - Screen is strangely divided so that animation has very little room
Path Stroke - Not all controls are visible with QVGA
BasicGraphicsLayout - layout is broken
Stylesheets - "About" Qt window doesn't fit to screen, and doesn't have scrollbars
DrillDown - even when '-smallscreen' parameter used, the details city view doesn't fit into screen
Vector deform - even when '-smallscreen' parameter used, the application screen is drawn so that controls take 75% and animation 25% which leaves the ball to behave in a spactic way in its narrow gap
ScreenSaver - Not relayouted to right orientation

Opened for internal QT-1031(some internal wiki links in that report).
