I looked into this today and found that the NVIDIA driver does not correctly generate damage events for a given window when the OpenGL rendering is actually happening to a child window. In this case, x11vnc is listening for damage events on the root, but Compiz is rendering to the Composite Overlay Window, which counts as a child window as far as this code is concerned. I'll try to fix the window hierarchy problem for a future release.
In the meantime, you can work around the problem by using Compiz's --use-root-window option, or by modifying Compiz to call XCreateDamage(dpy, cow, XDamageReportNonEmpty) to trigger damage events on the root window when it renders to the COW. -- Compiz / vnc screen refresh with nvidia-restricted driver/VirtualBox/ATI fglrx driver using X.org https://bugs.launchpad.net/bugs/353126 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in ubuntu. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : [email protected] Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
