I don't think we will need to check vendors often in this test. So I would prefer this condition to be (!strcmp((char *)glGetString(GL_VENDOR), "NVIDIA Corporation") && strcmp(winetest_platform, "wine")). This way you don't need to add an enum type and only change test_copy_context().

You can also add a Wine-Bug link to bug 54103.

Otherwise, this looks good to me. Thanks for looking into this.

There is also bug 51311 on AMD.
