[2.1.7] Visible planets in space have random lines/seams

When viewing space platform, the rotating planet images have some sort of seams that rotate with the planet itself. Its kind of hard to see in the images attached but when the planet rotates they are very visible, since they go with the rotation and kind of flash/shimmer in color constantly when moving. They disappear when the location rotates out of view. I so far checked Fulgora, Nauvis, and Vulcanus and they all have this. Not sure about other planets since I haven't unlocked them yet but i'd assume they have this issue too with the planet sprites.

When trying to reproduce, just look at the planet rotate, and give it a few rotations and you'll most likely see it. I seem to get it often but sometimes the rotations look fine, then the lines come back on another rotation.

For some additional details, I had the same happen specifically when using the Wayland driver on Linux. The issue went away after switching to X11.

Please post your log file so I can get your hardware info.

Here's my factorio-current.log. I saw the game got updated to 2.1.8 but the issue still appears. Hope this helps :)

Your log appears to be from Windows, so this isn't a linux-specific issue.

That reply about linux was from someone else, not me, if you're referring to that. But yea, I am on windows indeed.

I'm seeing this on Linux on X11, at least on Nauvis (I haven't checked whether it shows up on other planets for me). It only shows up at a specific angle; 90% of the time the planet looks fine. Attached a log file.

To add on. Personally, it doesn't matter what angle or distance I'm looking from, can still see the lines/seams and the shimmering of them from time to time on every planet. Not really an important bug or one that breaks the game but something you only really see when you're paying attention and looking directly at the rotating planets.

After watching a view rotations, the seams are always in the same place for all planets. Sometimes they are straight lines of longitude, other times they are jagged like in the video attached. But a given seam always looks the same (even across save files)

While platform_backdrop.planet_surface images are mapped to the sphere, the edge lines are sometimes visible.

The lines are the junction edges.

I'm using a mod to increase planet radius and those lines are sharp and visible.

Here in this video, after 40 seconds mark.
