I only mention it because in my experience I always have weird shit happening
when I upgrade xorg-server over a big version number change.
And rebuilding everything that underpins xorg always fixes it. Including
drivers and mesa.
In the old days when xorg was monolithic this never happened, as all the
drivers always got rebuilt anyway. Nowadays with xorg sources being modular,
we have to be a little more alert.
