The problem with what you're proposing is that, if the pixels are not read back by VirtualGL, then the VNC X server will not have a copy of the pixels in its virtual framebuffer. The lossless refresh, ALR, and interframe comparison features wouldn't work properly, since those features require

The final Goal is to do JPEG compression done by TurboVNC using libjpeg on GPU and not on CPU and in order to do that below is the given setup. We have a setup where VirtualGL interrupts all GLX calls and renders offline in a pbuffer on a NVIDIA GPU. In normal setup VirtualGL reads this rendered i
