<pre>As of "drm/i915: Refactor work that can sleep out of commit (v7)", commit hash
listed below, there is a lot of display flicker seen when cursor sizes change
on gen8.
The original fix was made here and is present in recent Chromium OS kernels:
commit 64f962e3e38bf6f40bbd2462f8380dee0369e1bf
Author: Chris Wilson <<a href="mailto:chris@chris-wilson.co.uk">chris@chris-wilson.co.uk</a>>
Date: Wed Mar 26 12:38:15 2014 +0000
drm/i915: Recompute WM when the cursor size changes
However, the recompute logic apparently got lost in refactoring, on around this
point:
commit 32b7eeec4d1e861230b09d437e95d76c86ff4a68
Author: Matt Roper <<a href="mailto:matthew.d.roper@intel.com">matthew.d.roper@intel.com</a>>

drm/i915: Refactor work that can sleep out of commit (v7)
Let's add the relevant code back. I'm rounding some edges on a patch, to land
on the mailing list soon.</pre>
