The mainline kernel did not change the behaviour. The bug still exists.
Could the bug be caused by some element in the Ubuntu graphics stack?

** Changed in: linux (Ubuntu)

Title:
  Hyper-V Synthetic Video Frame Buffer Driver not working

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  Hyper-V Synthetic Video Frame Buffer Driver was added upstream with
  kernel 3.10 (commit:
  http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=68a2d20b79b105f02dcbc52c211d7e62f98996b7)

  I am running Xubuntu 13.10 in a Hyper-V machine on Windows 8 Pro.
  According to the kernel module description the kernel driver should
  allow for FullHD resoltuion and should eleminate the double mouse
  curser. Here neither of that happens though, screen resoltuion is
  limited to 1152x864 like it was with 13.04 before the framebuffer
  driver was added and I still have double mouse cursers.

  lsmod verifies hperv_fb module to be loaded. So there must be
  something which stops the enchansments from working correctly.

  Fixing this bug is important to enable Ubuntu to run in Hyper-V
  environments, which likly to become more important with the includsion
  of Hyper-V in Windows 8.
