Separate X screen isn't accessible

[Mikhail Sviridov]

I use Linux Mint 14 Nadia 64 bit with MATE desktop. My video card is NVIDIA GeForce 310M
I have 2 separate X screens and the first one is the main and is at the left side of the second one.
Mouse pointer always wraps on the first screen from right to left while trying to access separate X screen by moving pointer to the right.
In this case the second screen is not accessible at all!
This bug had appeared after I made distribution upgrade.
There is some information about this bug here: https://bugs.freedesktop.org/show_bug.cgi?id=54654
