- DRI2&3/XPresent - configure --disable-epoxy --enable-xpresent
   Build Configuration for xfwm4:
     Xpresent support:             yes
     Epoxy support:                no

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.
