Anyone else been having any problem? It was working perfectly until up about the 2-20 snapshot release (whichever day had the pulseaudio updates – I don’t think they’re related, that just a change I remember).
Now, when it starts up, there is a black bar that is rendered over the panel and when I open an application menu, it’s only half rendered. Also, I can’t launch any applications from either the menu of panel, only via krunner. If I go to log out, the entire overlay for logging out is blacked out.
I did a fresh install of 2-27 just to make sure (KDE 4 install, then update to Plasma 5). SDDM is working fine, just not plasma.
It’s really odd. I don’t think it’s VirtualBox related either, as it works just fine in Kubuntu 15.04. It’s also working fine on actual hardware (mostly, I keep getting odd glitches on my AMD installed one).
