Attached is a simple Qt application which has two QScrollArea widgets in a QVBoxLayout. When running it in the S60 winscw emulator there are problems with the background wallpaper when the resolutions are switched.

In the attached screenshot 'initial.png' the inital state of the application is shown. The emulator resolution is QHD portrait 360x640 and everything is ok.

In the attached screenshot 'afterswitch1.png' the state of the application is shown after the emulator resolution was switched to QHD landscape 640x360. The wallpaper background is partly corrupted. Also a white area has appeared in the bottom right corner.

In the attached screenshot 'afterswitch2.png' the state of the application is shown after the emulator resolution was switched back to QHD portrait 360x640. The backgrounds of the widgets are misplaced.
