My Issue/Question:
Running the example for glfw with opengl3 with sanitizer flags seems to indicate that memory is leaked.

Standalone, minimal, complete and verifiable example: (see #2261)
Running the following commands:

cd examples/example_glfw_opengl3
CXX="g++ -coverage -fsanitize=address,undefined,float-divide-by-zero -fno-sanitize-recover=undefined -g -fno-omit-frame-pointer -fno-optimize-sibling-calls" make && ./example_glfw_opengl3

and closing the window shows the following output:

Hi

Personally don't think to a ImGui trouble (necessarily ): the references are all inside compiled libraries
Anyway I have tested your example in Fedora 34 with NVidia drivers getting this (similar) report:

Instead, in an other computer, always in Fedora 34, but with AMD drivers, i get this (somewhat different) report:

Disabling ImGuiConfigFlags_ViewportsEnable the report is almost similar (for me):

And is identical (with or w/o flag) with AMD GPU.

Tested also SDL version with same results.

@BrutPitt

    1. Can you test with the patch linked above ?
    1. Is the total amount mostly stable and independent of time elapsed (e.g. 3 seconds run vs 1 minute run) ?

@BrutPitt

  • i. With patch (forked imgui-features-opengl_buffer_update) have same report (with NVIDIA)
  • ii. The report is identical also over 5 minutes of run, and also the allocated system memory is stable
