Edward, my hardware is the new Thinkpad X230. Additionally i have configured several theming options. I remember he error did not occur in the standard theme.
Desktop Theme: Oxygen Colors: Krita-Dark You will have to use the system for a while as the error does not always occur. Maybe 10 minutes excessive window opening/closing/moving incl. browsing the web should be enough to trigger the trails. :-) -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to mesa in Ubuntu. https://bugs.launchpad.net/bugs/1041770 Title: Weird artefacts on screen (white traces, white boxes around windows) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mesa/+bug/1041770/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
