inconsistent mouse as virtualbox guest

[Matt Graham]

Linux Mint: 14 (Nadia) Cinnamon DVD install
Running in Virtualbox 4.2.4 r81684
Host system: Windows 7 64-bit Intel i7 2600K

Guest Settings:
4 Processors Enabled
PAE/NX Enabled
VT-x Enabled
Absolute Pointing Device Enabled
1024MB RAM
128MB VRAM
3D Acceleration Enabled

The mouse (not the cursor) randomly jumps (or is registered) as being at the top left corner of the screen.

Hot corners enabled:
The mouse sporadically jumps to the top left corner, activating the show workspaces hot corner. However, when moving the mouse after the workspaces preview appears, the cursor moves from the previously correct position (not from the top left).
Hot corners disabled:
With hot corners disabled and the cinnamon panel set to flipped (at the top), moving the mouse will randomly activate the cinnamon menu (changed to appear as hover state), with a click (left or right) being registered on the menu and not the location of the cursor as expected.
Dragging (moving) Windows:
Easily reproduced. Move any window. It jumps to the top left or to the top of the screen as you move it around.

Additional Info:
Mint 13 Maya running in the same VM has no mouse issues.

This bug is connected with X11.
Probably this commit fixes the problem:

http://cgit.freedesktop.org/xorg/xserver/commit/?id=3d1051aecbb1955084804133cacd12c7f696833a

There was no release since this commit so the only option is to wait for it.
I assume there is no way that xserver-xorg-core package maintainer (Ubuntu) will apply this patch before the release.

Temporary workaround is to disable VBox mouse integration.

Besides, FYI Fedora has this bug fixed in its package xorg-x11-server.

I thought it would be something further upstream than Mint. Thanks michalo2882 for checking it out (I'm no Linux expert)!
