The sample program required to duplicate the problem.

Description of Problem:
I have a simple test program that uses Owner Draw ListView control to display
grid. The program has a timer that repaints the grid every 1 second using
Invalidate. The program runs fine in Windows - starts up fast and repaints the
whole grid every second. 

However, when I run it on Mono, it takes several seconds to start. Once it
starts, it is very slow and does not repaint the grid.

Steps to reproduce the problem:
1. Run attached program called MonoTest without Mono and with Mono.
2) If you run it with Mono, observe that it takes very long time to start up.
Once it is started, the grid does not repaint.


Actual Results: expected it to run exactly as without Mono


Expected Results:


How often does this happen? always


Additional Information: The program was compiled in VS 2005
