Rendering glitches on outer planets in Linux on KSP v1.10.1

[sethmnielsen]

Not sure if this is the best place to report this bug. Let me know if I should report this elsewhere.

I was following the RO & RP 1 Installation for 1.10.1 guide exactly as written including the "Optional Visual & Sound Mods", and when I booted up to test I saw some nasty rendering glitches on Jupiter and Saturn (Uranus and Neptune have some issues as well, but they aren't nearly as bad). It's a noisy flickering that is really bad when far away, and gets progressively better as I zoom in until mostly disappearing when the planet takes up the full screen. At closer distances, the problem presents itself as several concentric circles of noisy static, and at farther distances the whole planet seems to be going haywire.

I have this problem in both the Tracking Station and in map mode during a game.

RSS with default visual enhancements, Jupiter:

To test if it was an issue with the visual enhancements, I tried downloading KSP v1.10.1 again and installing only Real Solar System (via CKAN with 8K textures). I didn't touch any of the graphics settings. The other planets look good now, but Saturn still has some flickering that is different from its RSSVE counterpart, but seems to be of the same kind of rendering bug.

RSS without visual enhancements, Saturn:

In this case, the bad rendering seems to occur only where the rings are occluded by the disc of Saturn. I also tried the 2K, 4K, and 16K textures, and it didn't make any difference.

Notes:

• On KSP v1.10.1 stock, I don't have the issue. All planets look fine, including Jool.
• I have tried RSS with and without visual enhancements on Windows (same machine) and I did not have the issue.
• I even tried running KSP for Windows through Wine on my Linux side, and I did not have the issue (though quite the drop in FPS, but that's a different issue of course).

OS: Arch Linux
Machine: ASUS ROG Zephyrus G14, CPU: AMD Ryzen 9 4900HS, GPU: NVIDIA GeForce RTX 2060 Max-Q

Any ideas on how to fix this?
