I am running a java application which creates a frame, pushes it to FS mode when clicking a button. On clicking the same button, the FS frame is restored to Normal. When I run this using the current PIT build on Cinnabar having an ATI Radeon 9600XT, I am seeing a VM crash as soon as the FS frame gets restored to Normal mode. This is not reproducible on Mustang-b37, not reproducible on the PIT build with OpenGL pipeline.

Here is the PIT build:
java version "1.6.0-2d.pit-jcg-win-03"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.6.0-2d.pit-jcg-win-03-java2d_26_may_2005_00_46-b00)
Java HotSpot(TM) Client VM (build 1.6.0-ea-b37, mixed mode)

I have attached a sample test. Execute it on Linux-Cinnabar with the PIT build. Click on the button. The frame will be pushed into FS mode. Click on the button again (or Press space bar). You would see a VM crash on the console.

Here is the crash info:
#
