Zooming on most bodies crashes the game

[Flu]

Game Version​

2026.6.2.4531

Operating System​

Linux NixOS with an AMD Radeon RX 6800M

What Happened​

On a fresh save, fresh install of the game, focusing on Pluto (or Titan, Mercury, Jupiter, Saturn, although not Mars or the moon) and zooming in, results in a crash. The freeze happens fairly close to the bodies. The actual angular distance at which it happens seems to depend on the body, but it may have something to do with the distance from the surface. Seems to affect multiple systems with Linux and AMD GPUs.

What Was Expected​

Expected behavior was zooming in until I could see the planet in its entirety.

Reproduction Steps​

1. Open game, no loading of any save, default values.
2. Press M for map view
3. Zoom out until the whole solar system is visible.
4. Either double-click on Saturn (and subsequently on Titan) or Pluto or the other planets affected.
5. Start zooming in (slowly or rapidly does not make a difference) until it crashes.

I can duplicate this issue on my device. Zoomed in to Pluto and crashed immediately. This was not present on my previously installed version, v2026.5.11.4462.

Still present for me in v2026.6.3.4568

Happens for me at least with Mercury and Ganymede on v2026.6.2.4531
Debian sid, Hyplrand 0.55.2, Radeon RX 9060 XT

I can't reproduce this on Windows with a R7 9850X / RTX 3080.

So is it an AMD issue or a Linux issue

 

[Flu]

@Kiwi Shark it's most likely both an AMD and Linux issue, I have not seen any Windows users complain about it (otherwise there would be a lot more posts) and everyone saying they have it also have AMD.

 

[JPLRepo]

The error GCVM_L2_PROTECTION_FAULT_STATUS: 0x701431 is an AMD GPU memory protection fault. It happens on Linux when your graphics driver or the Linux kernel tries to access a restricted or invalid memory address. It usually results in a frozen screen, game crash, or system reboot.

I've tried getting some actual crash info (w/ Mesa 26.1.2 and an RX 7600), unfortunately it seems like the driver recovers too fast and the detailed tool runs too late (and trying to disable recovery would be a pain since it'd entirely kill video output for monitoring the process), but the coarser information is pointing to somewhere in the DrawIndexedIndirect for planetary terrain rendering

I get this same problem on Windows.
