I've attached the problematic composition. Basically when I run this fullscreen and without the Render in Image it is excruciatingly slow, so I would like to render it at say 128x128 and then stretch that onto the screen but the results are buggy. Changing the subdivision (affects the render size) changes the way it glitches. Also if I remove the Clear patch from the Render in Image, I don't get the crazy black triangles, but it flickers like mad. I"ve played with the render in image settings but couldn't fix it. Is it a bug or do I need to change my GLSL code somehow? (works under normal conditions)
For me (Nov 2006 MB, IntelGMA950) disabling the clear patch makes it perfectly fine. So I'm guessing this is a bug. Also, tweaking the source seems to make it flip out and do weird stuff for me.
scaleX and scaleY might want to go in the vertex shader though, and pos should be a varying -- might make is a bit snappier, or maybe that's completely wrong (I didn't look too closely at the glsl code, I'm afraid)
