From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx> Remove redundant manual FBC nukes to avoid the GLK+ FBC nuke+disable+plane update fail and causing the top of the screen to become corrupted. A 100% workaround likely needs yet another vblank wait, but that's not entirely trivial to do without hurting interactivity, so for now at least try to avoid the issue for purely page flipped workloads.
