Hi,
A new x64-14 Salix. Everything looks quite nice.
I installed the Nvidia proprietary drivers, But I had to pre-install the kernel source from slackvare-14dvd,
also a usb_modeswitch package, cmake, and additionally slackvare64-compat32 packages.
Hell

only for Wine Package I had to install an old game ..

, also some themes from Vector.
In that sense, you may consider compatibility with the new multilib packages, because Gslapt wants to improve them ,
or aligns with others from the repo.
Or an extra CD with software, why not.
Everything is working very well.
During the installation cfdisk reported an error in partitions, but It has happened before with cfdisk. So trouble-free installation continued,
the partitions were prepared before, and it passed pretty well.
I almost forgot, the panel was set above, but is easy to move.
And QT V4L2 seems does not work.
thanks
