Landed here not too long ago. System called Deriso I believe, no idea what's going on with the terrain here. Playing on Ultra as well.

"Halo of lod loading", check.
Lack of rocks scattering and stuff, check
Flat like a table with the occasional sudden mountain, check
Blinking textures, check
Pop in issue, check
That's exactly my experience as well. Something's very broken and need to be fixed. But when I say that, apparently I'm a Doom cultist or something.
BTW, ObsidianAnt just posted a video, and it's not pretty :

And no, Mr ObsidianAnt, space isn't black. It's not generating much light, but it's full of stars. Billions of them. I see way more in Earth sky, with it's atmosphere than in ED. Mostly due to technical reason, I understand, but in Horizon it was perfectly fine.
The Milky Way from Earth is stunning. Not a redish stain you can barely see.
In short, space is dark but not black. In Odyssey, it's both.
Remember that ObsidianAnt tend to avoid any dramas and stuff, and is pretty positive overall. To have him make 2 relatively negative videos in a row, it's bad. It's around 20 Yamicks in the negativity scale.
Ironically, the planet he shows is the one that is pretty much a pattern for planet generation. His terrain generation was better than mine, but otherwise, that crater we briefly see in the video, is literally copy pasted on numerous world. That's mine : I stopped screenshoting eventually, but I saw more of them. Sure the color is different, but everything else look very similar. It's boring, and unrealistic.
Almost all those world are the same terrain than the gif you posted. Boringly flat with a few sudden mountain out of nowhere.
