If anything it's getting worse. Today I (unsuccessfully) spent a lot of time trying to figure out why the bottom panel's state won't persist between reboots. I don't even know what state it's reverting to. I never pinned Google chrome to that panel yet it appears there on every reboot while all my pins are gone. Some time was also wasted on rebuilding another panel that somehow broke and piled all of its widgets on top of each other and made them unclikable. There's also something seriously wrong with either the window manager or the compositor or both because on two occasions it sorta fused two windows together, producing a garbled mess that forced me to exit both applications and restart them.

I think I'll call this one a failure and go back to gnome as soon as I can. This really is not a good experience. Maybe in another two years I'll try KDE again. Last time I tried KDE it was much worse, so they're clearly getting better.
