I did not change any code from the GLFW+OPENGL example

[ocornut]

Hello,

I cannot seem to reproduce your issue.
Could you provide a call-stack? (as requested by the Issue template?)

You say "I did not change any code from the GLFW+OPENGL example"
However your screenshot shows a path of "tfm_seriousgame/bin/main_win.exe" which is not the filename of the example, so this is contradictory.

Can you repro in the unmodified examples/ application?

(PS: You can attach pictures/GIF in your github posts, prefer using github attachment over Gyazo)

I use my own makefile with the compiler MinGW 64 bits but the code in the main.cpp imgui.cpp etc. has not been modified. It also happens to me with GLFW+Vulkan. I have the lastest version of freetype and glfw, maybe it's the library version of glfw or another.
These are the compilator flags: -std=c++17 -m64 -Wall
These are the lastest versions of these libraries: -lopengl32 -lglfw3 -lfreetype -lgdi32 -static
A compilation comand looks like this:
x86_64-w64-mingw32-g++ -std=c++17 -m64 -Wall -g -c -Iinclude -Llib lib/imgui_widgets.cpp -o obj_win/lib/imgui_widgets.o -lopengl32 -lglfw3 -lfreetype -lgdi32 -static

Glfw3 and freetype are static but i tried changing it and it doesn't change the outcome at all.

I tried compiling it with Visual Studio and it works perfectly so maybe ¿minGW? No idea.

Here's the stack trace with gdb. I used the cygwin gdb debugger I suppose that's not a problem.

I hope that's enough info, if i can help in anything with this tell me! 👍

[ocornut]

Thanks for the callstack.
I think this bug existed for a few commits before 1.67 and then was fixed. Try updating your copy.

[ocornut]

I confirmed this bug was introduced by d845135 and fixed in b3469fa (Fixed on January 2nd). Sorry for the issue.

[pbc37]

Don't worry! I like imgui so I just wanted to help. Good luck!
