City rendering on densely citied small planets shows buildings in the sky

[syonfox]

Observed behavior

It looks like the city building rendering has a bug on small planets with many cities.

When you fly in close they properly snap to the ground but when in space near by 20-km ish they are rendering on a plane (see pic)

Expected behavior

Steps to reproduce

go to Deanus (7, 3, 1)

Klein's Rock

check out the city rendering

as i zoom in it seems the building get moved to the ground.

My pioneer version (and OS):
debian 11

6114ccb#diff-45521a7c36fc1cc7d274cedbca45979c0162f9e55ca8b8e6954e59c8fef693e1L754

maybe Im stupid and this is drawing the unrendered buffer... but i think its just drawing the border around the city

... i recompiled without this and still showing the same

other then that this branch is up to date with master but has some added stars for save file compatibility

this is the exact current version.

syonfox@d5525c5

(separate issue maybe this //SDL_setenv("SDL_VIDEODRIVER", "windows,wayland,x11", 0); ) is breaking some peoples builds are we sure it handles all cases/enviroments as best possible.

b376fa2 is not the hash of that release. Did you merge stuff into it?

Can you point to this mod/branch?

Are you absolutely sure you didn't touch any of the city stuff yourself?

I play on Linux Mint, pure vanilla, no modding of any kind. I see the floating buildings on asteroids all the time. It struck me as a minor issue since they snap into proper place before you can crash into them, but I can vouch this experience is presently basic to the game just like synofox's screenshots.

bizarre one this, just tested it with latest main branch and can confirm that it happens

Its still work in process but mod adds system faction and equipment as well as a ship.

Very much a work in progress but I don't think it crashes current version. but yeah I guess the system is needed for save game loading.

EDIT:
oops sorry, @zonkmachine asked about the exact release commit and now im considering if my deployment system verifiable back to the dev version I guess the closest i have is the commit it was uploaded but the zip could be from any tying I ran the deploy locally. I in theory need to also match information about the version of pioneer I tested it on. but this is a little off topic.
