Yeah that commit had a bunch of problems, many of which were subsequently
fixed. Do the issues still happen with git head? Or at least at commit
08ef36dc67 ?

For NV34, tutto completo ist kaputt.

For all other GPUs tested - AMD, INTEL, NVIDIA - DRI3/XPresent compositor is
actually recommended, it outperforms GLX compositor.

For NV34,
"tutto completo ist kaputt" - translated: all of them are broken.
