Re: not implemented: MIT-SHM/X_ShmCreatePixmap - do I miss a config option here?
Shared memory pixmaps have been disabled in NVidia's drivers for performance reasons. It's the same for most (all?) X.Org drivers in EXA mode.
It is possible to reenable them, but the right way to fix this is to fix wine.
Check out the "AllowSHMPixmaps" configuration option.
