After some time with moderate to high system load I get this message:

[163104.714192] [drm] nouveau 0000:01:00.0: no space while hiding cursor

This is a dualhead setup and I get one of those messages ever when my cursor
goes from one screen to the other. Concomitant I sometimes see a stuck phantom
cursor on the "inactive" screen.

It seems this message spewing begins after this fault:
