No, I've installed Unity 7.2.3 from trusty/proposed, but that did not fix my issue.
However I don't believe that this is the same bug. By looking at his screenshot, you can see that the line of pixels is separating his *dash* from the launcher, not his launcher and other windows (content). For me, windows can't get closer than that 1px bar to the launcher, i.e. it functions as a border. But the dash works fine, it's as close as it should be I believe - as you can see on the screenshot that I am attaching. ** Attachment added: "No 1px border between dash and launcher, only between launcher and windows" https://bugs.launchpad.net/unity/+bug/1373118/+attachment/4213307/+files/Screenshot%20from%202014-09-24%2010%3A46%3A05.png -- You received this bug notification because you are a member of compiz packagers, which is subscribed to the bug report. https://bugs.launchpad.net/bugs/1373118 Title: Vertical line of pixels separating the launcher from the rest of the screen To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/1373118/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~compiz Post to : compiz@lists.launchpad.net Unsubscribe : https://launchpad.net/~compiz More help : https://help.launchpad.net/ListHelp
