Version: (using KDE 4.0.83) Installed from: Ubuntu Packages OS: Linux I use Kubuntu with the KDE version 4.1b2. Sometimes Plasma not refreshes the desktop and failure, that is, inverts colors of the panel and until I unlock the widgets doesn't return to work normaly. Often when I open and close the openoffice (with the package "openoffice-kde" installed).
this is an upstream video driver bug.
