Description of problem
GNU/Linux: Trees and map objects disappeared in 1.3

What platform are you playing on?
Steam

What game version are you running?
1.3.2

Please select any/all DLC you have enabled.

Epirus flavor pack

Do you have mods enabled? No

Please explain your issue is in as much detail as possible.
Going from version 1.2 of the game to version 1.3 (and 1.3.2), all the map objects have disappeared (trees, rocks, etc.).

I am running GNU/Linux (Debian 10), I have attached the "systems information" data from Steam.

On this computer I am using a NVidia GPU, but the same is happening on another computer, with the same software setup, using an Intel GPU.

I already tried uninstalling the whole game and reinstalling from scratch. I never installed any mods!

Many thanks for your attention,

Steps to reproduce the issue.
Just start the game and play, there will be no trees and no other map objects.

The bug is still there in 1.4.1

The include "jomini/jomini_gradient_borders.fxh" breaks the shader.
I removed that line inside "gfx/FX/tree.shader" and also comment out the references:

//LOR-- float3 BorderColor;
//LOR-- float BorderPreLightingBlend;
//LOR-- float BorderPostLightingBlend;
//LOR-- GetBorderColorAndBlend( Input.WorldSpacePos.xz * WorldSpaceToTerrain0To1, BorderColor, BorderPreLightingBlend, BorderPostLightingBlend );
//LOR-- Diffuse.rgb = lerp( Diffuse.rgb, BorderColor, BorderPreLightingBlend );
...
...
//LOR-- Color = lerp( Color, BorderColor, BorderPostLightingBlend );

And have the trees and rocks back.

Here a little mod that does this trick. https://steamcommunity.com/sharedfiles/filedetails/?id=2045987121
