--- Comment #3 from Ben Anderson roothorick@new.rr.com 2009-05-09 03:03:30 --- Good call! Rendering is more or less correct with OffscreenRenderingMode=backbuffer, except for part of (what is presumably) the offscreen rendering appearing in the black bar above the image. However, performance takes a HUGE hit (5-15fps versus 45+).
