So i don't think this solution solve all the problem.Can you give an example of the problem with comples objects?
i don't have exemple here. but drawing somthing like a complex LSystem, when it takes 20ms to draw the shape, then it should blink. this is visible only if the rendering time is long.
of course, motion blur will make this less visible.
the aim of double buffering is to supress this problem...

I was using this patch:
this patch does not work on my computer : if i remove the objects nead to clear depth buffer, everything work as expected (i.e. not perfectly, but i see it's working).
Erich, could you try removing this 2 objects (gemglcleardeph and gemglclear) from the gemchain and tell us if it's working better? (do you also nead to destroy and then create the gemwin again?)
this is certainly why i was not able to use the stencil buffer...
anybody know why clearing the depth buffer clear also the rendering window?
