$25-50 USD / hour

I am working on a 3D Linux Compositor (the compositor happens to work in VR, but you do *not* need a VR headset to work on this project). Within the compositor, OpenGLcalls (like `glBindBuffers` and `glGenBuffers`) are allocating GPU memory without deallocating them. It's causing a VRAM GPU leak that I don't know how to fix. I need someone with OpenGL, Linux, and C++ experience to track down these calls within the code (there are about 40 of them) and figure out where the memory leak is occurring and to fix it. Linked to this project are some instructions of how to build the compositor, produce the the VRAM leak error, and some ideas as to what I think the problem is/how to fix it.

Hello, I am expert with opengl and c++ since more than 20 years ago... before award me the project, I would want to look at the code to be sure that I can do it in a short amount of time. Best regards!.

Hello. I have reviewed your errors. I think I can help you. You are using glew or glfw for gl extension? Could we discuss more? Thanks.

Hello, In the past I used a lot of OpenGL 1.1. I belonged to Russian gamedev communit with my own game engine based on OpenGL. For two years I worked as gameplay and AI programmer of Metro 2033 project. For a year I developed car navigation system that was rendered with OpenGL. Once I reverse engineered OpenGL calls of famous Dwarf Fortress game with glIntercept library to extend display grid (it was 40x25 grid). I intercepted OpenGL calls and replaced them with my own calls to provide greater than 40x25 grid. I think the most robust way to detect GPU memory leaks when code is available is to wrap relevant OpenGL calls with logger functions. But you should be aware that debugging the code can take much time. Maksym
