Hi folks,

I started using JOGL2 on a Win7, 64b computer. I retrieved a window-i586 release since Win7 is supposed to be able to run 32 bit binaries.
It seems that the depth buffer does not work properly: as shown by this image [1], the center of the gear is rendered before its edge:


 
When I turn around the gears, the gears are always displayed "sorted", meaning the blue is always on top of green, which is on top of red gear, which is consistent with a GL method calls in the sample program (red, green and then blue).I confirm that gl.glEnable(GL2.GL_DEPTH_TEST); is in the code.

I made the same test on a WinXP, 32b computer: it works properly, so Win7 or 64b suspected :) All these problems reminds me a related discussion concerning Jzy3d, using JOGL-1.1.1 [2], where a user does not have the feedback buffer working properly on a Win7, 32b computer.

If you see anything weird in my setting below, please let me know! Thanks in advance!
Martin
