Had time to experiment a little bit more. Turns out I can now only reproduce the rendering and font issues when the T450s is attached to the Ultra Dock docking station (which is how I most of the time use it).
When I remove the laptop from the Ultra Dock and reboot, everything seems fine. As soon as I attach it to the Dock again, rendering and font errors start to occur and seem to gradually get worse the longer I keep closing and opening apps. When booting with the laptop attached to the Dock it's worst and the system is utterly unusable right from the start. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1432194 Title: Graphics unstable on Ubuntu 14.04 and 14.10 using Intel HD Graphics 5500 To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1432194/+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
