UI is broken at one of displays. Fullscreen window creates only on display 0.

[Dreikblack]

If i drag or create window at 2nd screen ui is looks broken, button can be pressed tho.

Also if i try to create full window at non main display it's still appears on main one.

Editor UI works fine on all displays.

Main screen:

Second screen:

Third screen:

#include "UltraEngine.h"

using namespace UltraEngine;

shared_ptr<Window> window;
shared_ptr<Framebuffer> framebuffer;
shared_ptr<World> menuWold;
shared_ptr<Interface> ui;
shared_ptr<Camera> uiCamera;
shared_ptr<Widget> btn;
shared_ptr<Widget> btn2;
bool fullscreen = false;
int displayId = 0;

void initGui()
{
    auto default_font = LoadFont("Fonts\\arial.ttf");
    ui = CreateInterface(menuWold, default_font, framebuffer->GetSize());
    ui->SetRenderLayers(2);
    ui->root->SetColor(0.0f, 0.0f, 0.0f, 0.0f);

    uiCamera = CreateCamera(menuWold, PROJECTION_ORTHOGRAPHIC);
    uiCamera->SetPosition((float)framebuffer->GetSize().x * 0.5f, (float)framebuffer->GetSize().y * 0.5f, 0);
    uiCamera->SetRenderLayers(2);
    uiCamera->SetClearMode(CLEAR_DEPTH);

    btn = CreateButton("Change display", (float)framebuffer->GetSize().x / 2, framebuffer->GetSize().y / 2, 200, 200, ui->root);
    btn->SetFontScale(2.0f);

    btn2 = CreateButton("Fullscreen", (float)framebuffer->GetSize().x / 2, framebuffer->GetSize().y / 2 - 100, 120, 30, ui->root, BUTTON_CHECKBOX);
    if (fullscreen) btn2->SetState(WIDGETSTATE_SELECTED);
}

void changeDisplay()
{
    auto displays = GetDisplays();
    displayId = ++displayId;
    if (displayId == displays.size())
    {
        displayId = 0;
    }
    if (!fullscreen)
    {
        window = CreateWindow("Ultra Engine", 0, 0, 1000, 1000, GetDisplays()[displayId], WINDOW_DEFAULT);
    }
    else
    {
        window = CreateWindow("Ultra Engine", 0, 0, displays[displayId]->GetSize().width, displays[displayId]->GetSize().height, displays[displayId], WINDOW_DEFAULT | WINDOW_FULLSCREEN);
    }
    framebuffer = CreateFramebuffer(window);
    initGui();
}

int main(int argc, const char* argv[])
{
    //Get the displays
    auto displays = GetDisplays();

    //Create a window
    window = CreateWindow("Ultra Engine", 0, 0, 1000, 1000, displays[0], WINDOW_DEFAULT);

    //Create a world
    menuWold = CreateWorld();

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

    //Create light
    auto light = CreateBoxLight(menuWold);
    light->SetRange(-10, 10);
    light->SetRotation(15, 15, 0);
    light->SetColor(2);

    //Create camera
    auto camera = CreateCamera(menuWold);
    camera->SetClearColor(0.125);
    camera->SetPosition(0, 0, -3);
    camera->SetFov(70);

    //Create scenery
    auto box = CreateBox(menuWold);

    initGui();

    //Main loop
    while (window->Closed() == false and window->KeyDown(KEY_ESCAPE) == false)
    {
        while (PeekEvent())
        {
            const Event ev = WaitEvent();
            if (ev.source == btn && ev.id == EVENT_WIDGETACTION)
            {
                changeDisplay();
            }
            if (ev.source == btn2 && ev.id == EVENT_WIDGETACTION)
            {
                fullscreen = !fullscreen;
            }
            ui->ProcessEvent(ev);
        }
        menuWold->Update();
        menuWold->Render(framebuffer);
    }
    return 0;
}

I have two monitors set up and it works fine with this setup.

Can confirm:

#include "UltraEngine.h"

using namespace UltraEngine;

int main(int argc, const char* argv[])
{
    //Get the display
    auto displays = GetDisplays();

    //Create a window
    auto style = WINDOW_FULLSCREEN;
    auto window = CreateWindow("Example", displays[1]->position.x, 0, displays[1]->size.x, displays[1]->size.y, displays[1], style);

    auto ui = CreateInterface(window);

    //Main loop
    while (window->Closed() == false)
    {
        if (window->KeyDown(KEY_ESCAPE)) break;
    }
    return 0;
}

Fixed this part.

I am unable to produce an error where the GUI does not appear correct on a second display, using two monitors.

I am going to close this because there is no way for me to investigate this further. Please let me know if any new information arises.
