This morning I updated my F22 system (only stable Fedora repos), which included multiple Kf5 packages. After rebooting, I find that window redraws are frequently messed up. This happens both on switching desktops and simply raising a window on an existing desktop. Occasionally the switching process leaves traces of the previous desktop on the new one, and windows are only partially redrawn. Both switching and raising are accompanied by rapid flashing between the old and new states for a fraction of a second before settling down. I have an Nvidia graphics card, using the Nouveau driver. AFAIK Kwin was not one of the updated packages. I used to be able to look at /var/log/yum.log or run "yum history" to check, but dnf has changed all that though no doubt it's still possible somehow (the dnf manual is a model of obscurity on this point). poc _______________________________________________ kde mailing list kde@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/kde New to KDE4? - get help from http://userbase.kde.org
