Ah, yes, I remember tearing.  It SUCKS!  I dealt with it for years with 
my Nvidia cards.  I run KDE (Plasma, now days) and it has (had?) a 
setting to disable compositing for full-screen apps (like Myth).  Seems 
to me that fixed the problem, but I don't remember.  I also remember 
finding a CLI command that disabled it and I added that to my startup 
script for a while.  I switched to Intel onboard a couple of years ago 
and I'll never go back.  I'm glad to be rid of the extra heat and bother 
of the add-in Nvidia cards and the proprietary drivers and the extra 
cost and the tearing....
