Java 6.0 is working great! I am now able to switch screen resolution when using OpenGL pipeline!
The only weird thing (which was already in java 5.0) is that the first time my images are displayed, the colors are displayed in gray... This turn back into the real color as soon as they are displayed the second time. Do you know if there is a way to have them displayed in the real color at the first time ?
Thanks for the comments. Are you using an ATI board by any chance? There is a known driver bug where the red/blue channels are swapped in some cases, which may cause the gray issue you are seeing. Fortunately, this has been fixed in their latest Catalyst driver release, so you can download it and see if it helps.
In any case, please tell me which board/driver version you are using, just for the record.
