I get this message while playing FFXIV and then my graphics glitch out and the
UI disappears:

radeon: mmap failed, errno: 12

That floods the terminal when it happens with graphical issues, sometimes
though it will show in the terminal just a couple times with no issues, but
this usually leads to a flood of the error later.

I changed my ulimit -n settings to have a soft cap of 9000 and  hard cap of
65000 and the error is still occuring.
