Re: AW: Problems with tilesort SPU

I wonder if Java3D or the application is calling glFlush() without a 
current rendering context.

Try this change to tilesortspu_flush.c:

diff -c -r1.57 tilesortspu_flush.c
*** tilesortspu_flush.c 26 Jan 2006 00:13:51 -0000      1.57
--- tilesortspu_flush.c 5 May 2006 19:02:20 -0000
***************
*** 774,779 ****
--- 774,782 ----

         CRPackBuffer old_geometry_buffer;

+       if (!thread || !thread->CurrentContext)
+               return;
+
         CRASSERT(thread);
         CRASSERT(thread->currentContext);
         CRASSERT(thread->currentContext->State);
