Colour issue with post-process volumes

Looking for some help with a strange issue between post-process volumes (The red flashing) Apologies for the low quality GIF, but the red flashing in question is still highly noticeable, I wonder if anybody knows what might be causing this in particular? Thanks!

Here is a .gifv of the issue at hand: Imgur

Hi Sklarlight -

It looks like the known issue with reflections and Color grading. If you are using any Color Grading, try to disable it and see if the flashing goes away. In either case the issue has been resolved in 4.9.

Thank You

Looks like disabling the Colour Grading does indeed help it a lot, but I still have a subtle issue which seems to be caused by the highlight/shadow colour options in between volumes. Looking forward to 4.9!

Thanks, and all the best,
