hmm, what is the size you are currently using ?. It is quite hard to give advise as this is highly hardware and driver dependent. I would guess most will do a trial and error search for the acceptable size on their respective hardware. > Has anyone a idea with respect to the clearing operation? The problem is the PassiveBackground, which acutally does not clear anything, it relies on the application having cleared the (window) buffers. As the shadow stage render everything in it's own FBO but reuses the outside background is misses this clear. It is a general problem for stages and passive backgrounds. I'll see if I can find a solution where the stages blit the framebuffer contents into their FBO's. kind regards gerrit ------------------------------------------------------------------------------ Monitor your physical, virtual and cloud infrastructure from a single web console.
