snapshot of problematic dialog

In Chessbase 11, inputting incorrect security key details results in a dialog.
The panel that rests in it is not correctly drawn. In this case pictured the
white background does not fill the dialog, and sometimes is of different sizes.
Sometimes the message is missing. This happens every time. Using full screen on
a 4K display.

Suggestion of an incorrect (or order of) initialisation issue, 4K/screen size
issue or a data race?
