lshw output
After a kernel upgrade to 4.12, moving the mouse in some games under wine
(namely Mount & Blade Warband and Supreme Commander) causes the mouse cursor to
flicker and video performance to drop considerably (the screen remains frozen
while the mouse is moving), as well as cause some CPU load. Bisecting led to a
commit a5509abda48e:
commit a5509abda48ecfc133fac6268e83fc1a93dba039 (refs/bisect/bad)

drm/i915: Fix legacy cursor vs. watermarks for ILK-BDW
Steps to reproduce:
1. Install wine (tested with wine staging 2.19)
2. Install one of mentioned games (I only tested retail versions, but Mount
& Blade Warband demo might exhibit similar issues)
3. Move the mouse around after the game loads
Expected results:
Mouse moves without flickers or performance issues.
Actual results:
Mouse flickers, CPU load is increased. The screen is frozen until the mouse
stops moving.
Additional information:
My laptop has an optimus setup with an integrated Intel and discrete Nvidia
card. During tests I did not load the nvidia or the bbswitch driver and tested
with the integrated card only.</pre>
