Title:
Screen is stretched when using dual monitors
Status in Unity:
Confirmed
Status in unity package in Ubuntu:
Confirmed
Bug description:
When I'm in dual monitor mode (not mirrored mode; mirrored mode works
100% fine), the applications are stretched, and my mouse clicks don't
line up with the applications. See the attached image. Notice the
highlighted text in the webpage near the middle of the two screens. My
mouse was where the red dot was when I made that highlight. (The mouse
doesn't show up in screenshots I guess.)
I was supposed to have the application menu bar on both screens, but
it and the menus only show up on the right screen. They work fine
relatively, though sometimes as dropdown menus close they momentarily
visibly stretch like the applications are.

System information:
I was running Ubuntu 14.04 with the nvidia-331 drivers, dual monitor mode was
working great, but then in the last few weeks it started acting up like this
often. Probably related to some recent updates I guess. Logging out and back in
would sometimes fix it. I decided to do a full reinstall to 14.10, but now the
issue always happens.
The login screen and gnome-shell both work fine with dual monitor
mode. (I'll boot up my computer, see the login screen on my left
monitor with the background going to the right monitor exactly as it
should, I'll log in with Unity selected, and then it suddenly decides
to stretch everything ridiculously until I switch to single or
mirrored monitor mode.)
I do not get this specific issue when I use the default nouvea driver,
but I do get tons of graphical artifacting and the screen freezes
eventually when I'm in dual or mirrored monitor mode (single works
fine), so that's not an option for me.
I'm currently using the nvidia-331 version 331.113-0ubuntu0.1 package.
I've tried downgrading to nvidia-331 version 331.89-0ubuntu5, and
adding the xorg-edgers PPA and upgrading to nvidia-346, but the exact
issue persisted.
