libgdiplus-1.1.13.2-2

Steps to reproduce the problem:
1. Compile attached source code and run on a Mono framework
2. Compare with MS .NET framework
3. 

Actual Results:
The clock is redrawn a number of times and fails to work unless the window
is resized and then it only works for a couple of seconds

A single clock should be seen

How often does this happen? 
Always

Additional Information:
Tested on a MS .NET framework machine (WinXP). Worked fine. Reported upstream BZ
