Public bug reported: This is exactly same as LP #1120223 which has been closed by mistake:
[How to reproduce] 1. Have a dual screen left-right config, with the Launcher just visible on your main (left) monitor 2. Make your mousepointer move between first and second display multiple times [What you would expect] You should feel no barrier when doing that, as there is no Launcher on the right screen. [What actually happens] The mousepointer sometimes hangs, when moving between those screens (both directions are affected, left->right && right->left). Note: It always hangs once you stay longer than 1 second on each monitor. It also starts blocking after one second if you move between your screens rapidly. ** Affects: unity Importance: Undecided Status: New ** Affects: unity (Ubuntu) Importance: Undecided Status: New ** Tags: raring regression-release ** Also affects: unity (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/1161726 Title: Multi-monitor: Mousepointer hangs when passing between monitors, although no Launcher is there (regression) To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/1161726/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
