Description

RenderVKVolCloudTemporal causes ghosting on dark setting windlights. Involves volumetric clouds. May only be at certain elevations. Turning the above mentioned setting solves or reduces the issue.

Steps to reproduce

Set VKVolCloudTemporal. On by default. Setting off reduces/eliminates ghosting. Twist view around in dark settings or run..
