Title:
  Mouse pointer corruption, radeon, dual-head

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  Since upgrading from quantal to raring, I am experiencing corruption
  of my mouse pointer around once per day.

  I am using a dual-head setup on an ATI RV730 GL [FirePro V3750].

  When corruption occurs, the mouse pointer is usually some garbled
  rearrangement of the pointer's pixels when the pointer is on one
  monitor, becoming invisible when shifted to the other monitor.

  Symptoms are a lot like
  https://bugs.freedesktop.org/show_bug.cgi?id=55819 except raring's
  kernel is a lot newer than the change referred to there, and I haven't
  managed to locate any specific screen areas which affect the behaviour
  I am seeing.

  Unfortunately I am not able to reproduce corruption on demand, it just
  happens from time to time during normal use.
