I was going to submit a bug report but thought I’d see if the problem is with something else first.
On these images effects:
Sun Shafts
Contrast Enhance
Edge Detection (only when advanced is checked)
Edge blur
I get vertically flipped artefacts, some of which like the edge detection flip back to normal when other check boxes are checked and some flip back when used with another flipped image effect eg. sun shafts and edge blur seem to flip back, but i do still get odd shapes ghosting on my skybox.
Is this something you know about or is it a new problem that needs a full bug report?

I get image fx conflicts too, first noticed it when combining ssao with sun shafts and edge blur. I’ve submitted a bug as well. I imagine it has to do with the depth buffer, as some image fx use the depth buffer while others don’t (and get no conflicts with).
