------- Additional Comments From ivg231@gmail.com 2006-15-09 20:35 ------- Please try setting pbuffer_support=TRUE in device.c, and let me know if it fixes the problem. The renderUpsideDown flip is now applied separately in the offscreen and onscreen case (instead of always in the common path). However, offscreen case is disabled completely if pbuffer_support = false. One could argue this is the correct approach - either offscreen works completely, or not at all.
