Strange Artefacts with Sharpening

[tobiasweisercg]

i just discovered a strange bug when using Sharpening/Blurring:

Framebuffer looks great but the saved EXRs show some strange horizontal and vertical artefacts when there is a bright light source…
if i disable Sharpening, everything works fine.

Edit: Corona 1.7 Hotfix 2

I couldn’t reproduce this.
Can you post your bloom, glare, sharpen, blur settings from the VFB?
Also could you share a problematic scene like this with us?

yep, should be fixable if we get scene

More infos:

i increased the gamma a bit in post… so the artefacts are more visible…
