The Xorg Edgers PPA fixed the Steam dialogue box corruption and no corruption showed on the Kerbal Space Program, but as you can see from the latest screenshot there are horizontal lines on all three screens.
I found that they appear when you hold a window such as the file explorer and while grabbed drag it left to right and these lines appear. Though if you left click the desktop outside the window the corrupted lines disappear. They reappear upon window movement actions such as dragging. ** Attachment added: "screen horizontal corruption only - xorg edgers ppa" https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1260827/+attachment/3942812/+files/xorg%20edgers%20Screenshot%20from%202014-01-07%2015%3A45%3A53.png -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1260827 Title: HD 5970 screen corruption multi monitor To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1260827/+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
