Title:
  Cursor bleeds on the platform with Mali armsoc driver

Status in OEM Priority Project:
  New
Status in OEM Priority Project focal series:
  New
Status in xorg-server package in Ubuntu:
  New

Bug description:
  [Impact]

  The cursor bleeds because of the bug in xorg which does not refresh the sprite background. (LP: #1911479)
  The issue happens to Xilinx zcu102/104/106 boards (arm64, mali gpu).

  [Test Case]

  Check if cursor is still bleeding with the patched xorg-server

  [ Regression potential ]

  The new function, miDCSaveUnderCursor2, is only used by Xilinx armsoc driver.
  It won't impact other platforms.

  Xilinx is trying to upstream the patch. It's still under review.
