So to give a little more clues into what I'm saying. I noticed on a earth biome that when i started the game and was zoomed in between the ground and air levels, the screen would slowly flicker between normal and a darker shade of grey and back to normal. At the Orbital zoom level it stopped flickering but was only between the ground and air levels it was noticeable. This happened on other planet biome types as well. Anyone else experience this?
I not sure if this same problem, but I think you should try workaround varrak posted: https://forums.uberent.com/threads/hdr-glitch.55730/#post-856170 It's wasn't included in 59607, but should be in next update.
