Hi @FreePhoenix888,
Thanks for reporting.
I can't reproduce that, does that always happen? Could it be related to some graphics cards issues on your side?
For me building and running from powershell runs ok.

Hi, @czoido ! What information could I provide to help us find it out?

To be honest, I'm not sure, what could be happening... A couple of things that may give us some hints...

• If you resize the window, does something appear?
• If you launch the exe from the windows explorer, does the same thing happen?
• Are the shader files there besides the executable?

In the video you may see that

• 2 shader files are located with exe file
• I am unable to resize window
• The same happens if I launch by using explorer

Additional Info:
examples from official imgui repo are working for me, at least these:
https://github.com/ocornut/imgui/tree/master/examples/example_win32_directx11

This project uses opengl, are the opengl ones working for you? Maybe it could be some missing dll's?

[FreePhoenix888]

opengl: glfw and win32 examples were working
Sdl is not because is not installed. As I see glfw and glew is user in this project
https://github.com/conan-io/examples2/assets/66206278/90bb78e8-2a16-44eb-afe3-786b9c82b507

Is there more info I can provide to find out are there missing dlls?

[czoido]

Maybe you can try to run the imgui example for opengl + glfw in case it is something wrong with the code. Try replacing the main.cpp from this repo with this: https://raw.githubusercontent.com/ocornut/imgui/master/examples/example_glfw_opengl3/main.cpp and build again.
Be aware that you have to add the path for the binding includes to build successfully:

#include "bindings/imgui_impl_glfw.h"
#include "bindings/imgui_impl_opengl3.h"
