This happens most of the time (I can reproduce it 90% of the time) that, for example, I take the mouse cursor to the absolute top-edge of the screen above the Unity top bar, and move the cursor from left to right, or right to left, there will be white dash like (---), or dot like artifacts, ALWAYS in proximity to the cursor. Where I take the cursor, the artifact goes with it and flickers.
1) The release of Ubuntu you are using, via 'lsb_release -rd' or System -> About Ubuntu
Description: Ubuntu 12.04 LTS
Release: 12.04
2) The version of the package you are using, via 'apt-cache policy pkgname' or by checking in Software Center
I don't know what package to mark this as. The problem affects the Unity top bar.
3) What you expected to happen
No artifacts or glitches
