I am running an application which opens up a frame in FullScreen mode and displays all the display modes supported by the default GD. My current display mode is : (1024, 768, 32, 60). I am selecting (640, 480, 32, 60) display mode and clicking 'Set Display'. The display mode is set properly. Now I am selecting (640, 480, 8, 60) display mode and clicking 'Set Display'. As soon as I call GD.setDisplayMode() the VM crashes on the PIT build with OGL enabled.

I am running this on WinXP-Prof sp2 which has Nvidia GeForce4 MX4000 video card with 77.77 driver. This crash is seen only on the PIT build. On the promoted build (Mustang-b50), I am getting a ClassCastException which is given below:

Exception on Mustang-b50:

FS frame turns black when changing from 32 bit to 16 bit display mode (Say from (640,480,32,60) to (640, 480,16,60) on PIT build as well as Mustang-b50).

Here is the PIT build:
