I don't think Matrox provides CUDA functional.

@Ewen, by the way, this mail pushed me to another thought the leak
could possibly be in userspace driver — Matrox doesn't seem to use
Mesa, so I know basically nothing about them. I tried googling a bit,
and barely the first link is this
https://www.centos.org/forums/viewtopic.php?t=57699 "Xorg Memory Leak
with Matrox G200eR2".

So yes, it is very well possible the leak not because of XServer, but
rather bug in Matrox's driver. In this case upgrading Xorg won't help,
you need to get support from Matrox.
