Not sure what's going on here, but a lot of model thumbnails look like this.

Material previews do not have this problem and look normal

I wonder if its because the model thumbnail is rendered using an ortho projection....

This example shows the problem. This occurs with an ortho camera when the near range is less than zero and the object is behind you. I'm not even sure this is a bug, it might just be an unexpected mathematical outcome, but I think I can prevent it from happening: 

#include "UltraEngine.h"
#include "Components/Motion/Mover.hpp"
#include "Components/Player/CameraControls.hpp"
#include "Components/Player/FirstPersonControls.hpp"

using namespace UltraEngine;

int main(int argc, const char* argv[])
{
    auto cl = ParseCommandLine(argc, argv);

    RegisterComponent<Mover>();
    RegisterComponent<CameraControls>();
    RegisterComponent<FirstPersonControls>();

    //Get the displays
    auto displays = GetDisplays();

    //Create a window
    auto window = CreateWindow("Ultra Engine", 0, 0, 1280, 720, displays[0], WINDOW_CENTER | WINDOW_TITLEBAR);

    //Create a world
    auto world = CreateWorld();

    //Create a framebuffer
    auto framebuffer = CreateFramebuffer(window);

    world->SetEnvironmentMap(LoadTexture("materials/environment/default/diffuse.dds"), ENVIRONMENTMAP_DIFFUSE);
    world->SetEnvironmentMap(LoadTexture("materials/environment/default/specular.dds"), ENVIRONMENTMAP_SPECULAR);

    auto plg = LoadPlugin("Plugins/FITextureLoader");
    auto model = LoadModel(world, "https://raw.githubusercontent.com/KhronosGroup/glTF-Sample-Models/master/2.0/DamagedHelmet/glTF/DamagedHelmet.gltf");

    auto camera = CreateCamera(world);
    camera->SetDepthPrepass(false);
    camera->SetClearColor(0.125);
    camera->Move(0, 0, -2);
    camera->SetProjectionMode(PROJECTION_ORTHOGRAPHIC);
    camera->SetRange(-100, 100); 
    camera->SetZoom(125);
    
    camera->AddComponent<CameraControls>();

    //Main loop
    while (window->Closed() == false and window->KeyDown(KEY_ESCAPE) == false)
    {
        world->Update();
        world->Render(framebuffer);
    }
    return 0;
}
