I have an X11 double buffer (DBE) client that does animation using the
Mac OS 10 XFree86 Xserver. The buffer swapping on Mac oubviously does
not sync with vblank as I can see tearing effects in the application
window. (The same application works fine on Solaris Sparc where the
buffer swapping sync with vblank is done at the graphics card driver level.)
My question:
On Mac OS 10, is there a way I can sync my application to the vertical
retrace of the screen in order to suppress these tearing effects ?
The system used is a 17-in Aluminum Powerbook, 1.33GHz processor speed.
The OS is Mac OS X 10.3.2
Thanks !
