    Hello,

    I'm using a render texture to render my scene using the Post-Processing Stack v2.

    It works fine till 4096x2048. But at 8192x4096, the Ambient Occlusion's Multi-scale Volumetric Occlusion gives darkened lines on the planes facing the camera, which prevents to do hi-res screenshots of my game.

    Did I hit some hard limit in the AO shader ?
    Is there any way to fix that ?

    Note: the Scalable Ambient Obscurance works fine, though, but it's not a suitable replacement as it creates weird outlines whatever the resolution is.

    Also having this issue, preventing me from rendering my animation projects at 4k at the moment. Interestingly enough, the line issue is caused at 4k for me and not 8k. Will keep you posted on my progress.

    As of Feb 2020, the newest version on Github does not fix this.

    Hello,

    I meet the same issue with postprocess AO when we make a render in 4K.I tried also with the newest version (3.1.1) and this version does not fix this.

    Anyone have info regarding this problem?
