--- Comment #25 from Francisco Garibaldi fgaribaldi@linux.com 2010-08-07 02:33:05 --- I tried with conditions
OffScreenRenderingMode = fbo Same result as using backbuffer, render is upside down
OffScreenRenderingMode = pbuffer No render at all, black screen, only 2D elements are showed
I hope this might help
