Bug Description
Yesterday I have recently received update to my Kubuntu 12.04 install with KDE 4.10. Immediately after the upgrade and login back to the desktop, I have noticed artifacts on the desktop as highlighted in the attached screenshot. They seem to be related to virtual terminal, since the while dots area actually blinking like a terminal cursor.
My mouse cursor have also disappeared on several occasion. When that happens even the keyboard becomes unresponsive after a while.
Both of these issues are happening on 3-way multiseat system only on the primary seat. I can kill the X process from the other seat and when the X restarts I regain control over keyboard and mouse, but the artifacts are still present.
I have performed additional testing to confirm that this defect is related to upgrade to KDE 4.10. I have upgraded my Kubuntu 12.04 to 12.10. That installed the default KDE shipped with 12.10. Everything worked fine without any artifacts. Then I added kubuntu backports ppa and installed the latest kde 4.10. After restarting I have the artifacts on the main screen. Nothing else have changed on the system other than the kde 4.10 upgrade.
