--- Comment #14 from Ville Syrjala <ville.syrjala at linux.intel.com> ---
The real problem is most likely in i915 code, and it should be fixed by my g4x
watermark rewrite (once I get around to posting them, and we get the into the
tree).

As the system memory self residency goes up the more likely we're to see the
problem on the display side, which probably explains why scheduler changes can
end up masking/unmasking the problem to some degree.
