Default 260.xx drivers break Java2D OpenGL pipeline

I have been using the Java2D OpenGL pipeline for some time with Java 1.6 on 64-bit linux on several machines with 173.xx, 180.xx, and 195.xx versions of NVIDIA drivers. I haven't had any problems until now.

A few days ago I began trying the new 260 series of drivers. I have tried 260.19.06 and 260.19.12 on 2 machines running Debian 5.0 and Ubuntu 10.10. One machine has an 8400 GS, the other has a Quadro FX 550. The Java2D OpenGL pipeline worked flawlessly on both machines with older 173/180/195 drivers. I am using Sun Java 1.6.0_22 64-bit. Both machines are running 64-bit kernels.

With the 260.xx drivers, on both machines I see the following problems:

1. If I just set -Dsun.java2d.opengl=true, I see all swing frames are empty - no widgets are drawn (see empty_java2d_opengl_window).

2. If I set -Dsun.java2d.opengl=true and -Dsun.java2d.opengl.fbobject=false (disable frame buffer objects) this works around problem #1 and widgets are displayed (although this has known performance impacts)

3. In either case #1 or #2 (sun.java2d.opengl=true and sun.java2d.opengl.fbobject is true or false), when I close the Java GUI application the X server almost always (but not 100% of the time) crashes with a segmentation fault that involves nvidia_drv.so (captured from /var/log/Xorg.0.log):

I have a workaround for now in using an older 173/180/195 series of drivers, but I am concerned about the future of the Java2D OpenGL pipeline if it is broken in the current release.
