Re: 1.0-9631 Composite (6.9.0) and GLX problem
After updating to Xorg 7.3, FBSD stable 6.2, and Nvidia drivers 100.14.19, composite+GL now works for me. I also applied the mutex patch discussed in another thread.
OpenGL applications, in general, appear to work a lot better now. Even without composite enabled, I used to get "stuttering" in the GL application when another application updated a window. This doesn't seem to happen anymore -- or at least it is significantly less frequent.
