I am having this issue as well. I have no idea how the final release made it "out the door" with this bug.
I've attached a screenshot -- my deadzone is the area where my mouse is located, the full width of the screen. (ie, for any "x" coordinate with that specific "y" coordinate, my mouse is not functional -- no clicks, no scrolling) It's incredibly frustrating. I look forward to seeing a fix for this odd bug. ** Attachment added: "screenshot with mouse pointer indicating deadzone" https://bugs.launchpad.net/light-themes/+bug/741112/+attachment/2104960/+files/deadzone.png ** Also affects: compiz Importance: Undecided Status: New ** Also affects: compiz (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/741112 Title: Dead zone on the screen -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
