ImGui package not working

[MechSlayer]

Hi, I tried to use the ImGui package following the Lab/ImGui example, but for some reason is not showing anything.
I tried using OpenGL 4.6 Core with a GLFW window.

Here is an example

//ctor
// window.View is a IWindow, and window.Input is a IInputContext
GuiController = new ImGuiController(glContext, window.View, window.Input);

//OnRender
GuiController.Update((float) deltaTime);
GlContext.Clear((uint) GLEnum.ColorBufferBit);
ImGui.ShowDemoWindow();
GuiController.Render();
Window.SwapBuffers();

Either remove the extra SwapBuffers call or disable ShouldSwapAutomatically in WindowOptions

What driver are you using?

Latest AMD Adrenalin, the GPU is an RX 580

Try running RenderDoc to see if you can find out which function is failing, which would help us a lot.

Also, check the output of gl.GetString(StringName.Version)

This is the output of GetString 4.6.14757 Core Profile Context 20.12.1 27.20.14501.28009.
Looks like all glDrawElementsBaseVertex are failing, this is the description of the error

No vertex buffer bound to attribute 0: in_color (buffer slot 0) at draw!

same goes for attribute 1, and 2, and for in_position and in_texCoord.
I can send the capture if you want.

Yes that’ll be helpful :)

Okay, I think the NuGet package has something wrong, because compiling the ImGui extension project works, but using the NuGet one fails.

It's worth noting we've recently rewritten the ImGui extension, so 2.4 will have a brand new implementation which should be compatible with your existing code and fix your issue.
