Looks like dependency problems in the python libraries. But since first reporting, in the meanwhile I used Kubuntu Backports to upgrade to plasma 5.5.3, qt 5.5.1 and I am running kernel amd64 4.4.0-040400-generic from ubuntu kernel ppa.
I also tried newer xorg from xorg-edgers and oibaf. All of this changes nothing. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1509434 Title: Kubuntu panel, starter, desktop do not redraw on change using EGL in kwin To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1509434/+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
