I tried unity --reset and changed back to wobbly windows...Now the problem not occured till now.. I think it corrected.... :-)
But now i noticed another problem...I am not sure about when it began to appear.... when i right click on the unity dash icons a pop up menu appears....but i am not able to select the menu items... So i needed to right click again... then the menu items are clickable (sorry for the bad english) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/914616 Title: window borders not showing sometimes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unity/+bug/914616/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
