  While using recordmydesktop and switching windows with alt-tab I get errors like
  "Locking assertion failure"

  The resulting file seems to be rather ok (but quality is bad in the
  moments when the above error happens - movie lags for 1-2 seconds).

  Dualcore amd64 ubuntu 8.04 up to date, nvidia binary driver (glx-new)
