QCheckBox: Windows Mobile 6.0: check mark is out of proportion to the check box when run at VGA resolution in either an emulator or hardware

The attached image shows the problem. Check mark is shown incorrectly at 480 x 640 resolution on Windows Mobile emulator and on target device using Windows Mobile 6.0.

Any code sample with a QCheckBox reproduces this.

The attached zip file contains a demo application and a screenshot showing the problem.

To reproduce using the attached application, run it then click the menu button. On the dialog that appears, click the button at the top right (to the right of the line edit) to hide the keyboard. You can then see the checkboxes - check one and you'll see that the check mark is about one quarter of the size it should be.
