> mrobinson pointed out on IRC that after fixing Bug 80509 the GTK port passes the stress test https://cvs.khronos.org/svn/repos/registry/trunk/public/webgl/sdk/tests/conformance/context/context-creation-and-destruction.html ,, although it runs slowly -- and they were running on NVIDIA hardware, e.g. a real GPU. So it's possible there is a dangling pointer in the Chromium implementation that prevents these resources from being collected efficiently.

Anyone working on this?
If no, maybe i can do investigation and some experiments according to your suggestions and then try to draft out one patch.
