Xorg when run as a daemon from sddm should not touch any files under /root.
As an aside the system has only had one user login and that user was not root.

Stashing files in /root/.cache seems like a really bad idea.  My first take on this was it was a likely virus.

This seems non compliant with Filesystem Hierarchy Standard (FHS)

sddm could set MESA_GLSL_CACHE_DISABLE=true to disable the cache,
nothing here for the Xserver to do.
