[CentOS] what writes to /root/.cache/mesa ?

Dear All,

I have several CentOS 7 machines (but not all of them) on which I have 
noticed that something gets written to

/root/.cache/mesa

every so often (once every several days). It is my understanding that 
mesa is related to GUI (X11), but on these machines (on neither of my 
machines, actually) root never logs in to GUI X11. I may have remote 
root logins with Xforwarding though. Hence my puzzle: what is that that 
writes to /root/.cache/mesa? Some, but not all of occasions seem to 
happen upon machine [re]boots.

Thanks.
Valeri

PS This gives me dejavu. A while ago when people started demanding to 
have google chrome browser installed on their workstations I had hard 
time to get rid of google's cron jobs that were writing where only root 
should - without explicit permission to do so. Dough. Somebody's 
software thinks it is smarter than everyone who uses it... "Machine 
learning" all the way ;-)
