This problem happens 'out of the box' using nothing more xubuntu trusty iso installed on two systems, one running virt-manager and the other hosting vms. So far, so good.
To reproduce: try a standard xubuntu amd64 install on a vm guest using qxl as the video driver and spice as the display system. Somewhere during the install questions to do with disk use, every second or thid letter randomly just disappears. "Removing firefo " a few dozen times,. Removing kpart redisplayed a few dozen times. The 'Thank you we'd love to hear about your experiences' screen has title "In ta". Trusty / qxl / spice on vm guests is compeltely unusable. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-qxl in Ubuntu. https://bugs.launchpad.net/bugs/1261916 Title: Missing letters in spice client session with KVM guest To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-qxl/+bug/1261916/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : [email protected] Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
