Raytraced AO Screenshot problem

Please help! I’m having an incredibly frustrating issue with the screenshot tool and ray-traced AO. Just running in window, the image is clean, and resolves well. However, when I take a screenshot using the highres console command, the AO pass renders over the frame at the wrong scale.
This is how it renders out, vs a snip from my monitor:

I’ve tried just about every varation of commands, window size, screen percenntage etc I could think of. I also tried the regular camera (these are from cinecameras) and the screen capture component, but there just doesn’t seem to be any difference. Screen percentage does change the scale of the AO frame relative to the window, but it doesn’t ever completely line up.

I’m so lost at this point, and have a massive number of frames to output. Please help. You’re my only hope!

I suggest you using the Nvidias Ansel for the taking the screenshot.
