JDK-5033205 - PIT: OGL with Java2Demo and Radeon not displaying application demos properly
Description
I am drawing 3 filled rectangles to an offscreen image and the rectangles are filled with solid red, blue and yellow colors respectively. When I run this on Linux with opengl flag, red and blue colors are swapped and yellow color appears as light blue. This is noticed only on the following 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_15_apr_2005_02_14)
Java HotSpot(TM) Client VM (build 1.6.0-ea-b32, mixed mode)

Not reproducible with default mode. Not reproducible with Mustang-b31 on OpenGL. I have attached a screenshot of the same. I reproduced it on Cinnabar with ATI Radeon 9600XT. This is not reproducible when drawing directly to the screen.

I have attached a sample test. Execute the sample test on linux with OpenGL flag. If you see the colors appearing incorrectly, the bug is reproduced.

EVALUATION This issue is due to the fix for 6240664, which makes createImage() return a regular managed image (similar to what GraphicsConfig.createCompatibleImage() would return). This problem is specific to ATI's drivers on some boards: when rendering an texture to the screen, the red/blue channels are sometimes swapped. This issue was filed with ATI but there has been no resolution yet. It is already tracked under 5033205 (which covers a few different ATI driver problems), so I'm closing as a duplicate of that one. ###@###.### 2005-05-02 15:12:33 GMT
