OpenGL Windows drivers for Intel HD 630 leaking GPU memory when using shared contexts

yosoymin — Mon, 26 Apr 2021 06:40:00 GMT

The way to reproduce this memory leak is to create a shared context, then create some textures on that shared context (should be more than one texture), then change to the main OpenGL context and destroy the previously created textures. If you do this process in a loop, you will see that the GPU memory grows very fast.

I've done a simple program in github that reproduce this, so you can try and reproduce: https://github.com/yosoymin/InitGL/tree/intel_shared_context_leak

This program runs ok in older versions of Intel drivers (27.20.100.8681 tested in a Intel HD 655 and HD 630) and aslo in Linux or with other vendor drivers.
