I'm having some issues with this update.
After startup ciinnamon crashed immediately. Restarting the desktop or rebooting didn't help.
Gnome-desktop started, but the panel and osd were completely transparent with arc-gtk-theme.
Guake-terminal didn't start anymore. Reinstalling arc-gtk-theme und guake didn't solve the issues.
Unfortunately, I need my machine for work now, so I don't have time for tracing the issues at the moment.
Thus, I went back to stable for now and everyhing is working as expected again.
I'm using linux49 and I'm on intel-graphics. Anybody else with a similar experience?
