I think this is happening because when Xvfb calls driCreateNewScreen2(),
it ends up trying to use the D3D12 driver, which fails to load, but then
tries to dlclose() a NULL handle during teardown.
Workaround: run tests with LIBGL_ALWAYS_SOFTWARE=1 in the environment,
which causes Mesa to skip the D3D12 driver.
