apparently, I can reproduce even without rebooting. As i can't capture this in video from within, I used my camera: http://people.ubuntu.com/~fta/chromium/bug795995.ogv It's ugly but it shows the problem.
I started from a webapp (GReader), i clicked on a link, it created a new window in which it restored my previous session. In that session, I had the link from comment #2 (the google ipv6 page), which contains a chart in flash. It includes a corrupted xterm. And at the end, when the problem disappears, i just gave the focus to the tab owning the charts. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/795995 Title: flash ghost in the top left corner of the screen To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/795995/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
