OS: OpenSuse Tumbleweed with KDE. Icon Theme: Reversal
I used the Latte Dock before but since it didn't play nice with Wayland and is basically unmaintained now, I simply transformed a KDE Panel into a Dock. I use a KWin Script called "Panel Auto Hide" to make the Dock disappear when window hits it.
Not OP, but I've been running TW for... 5-ush years now, I think, and it's been great. Even when I still had Nvidia hardware and sometimes ran into a kernel being too new or whatever it was that made the Nvidia driver shit the bed: roll back to the previous snapshot, wait for a couple of days. Apart from that it's been pretty much rock solid.
The only thing I might switch to, is Kalpa.
