When I tried it a year ago, printer setup failed with a permission error until I disabled the firewall, and I had to install a community repo by a random person and manually edit a text file to get airprint and airscan working. Half the YaST modules didn’t seem to do anything or work correctly, or duplicated KDE settings. That’s what I consider to be “annoying visible bugs”.
I also find their software selection to be limited (without said random community repos), and you can only update Tumbleweed from the command line. It felt like an unfinished mod of their flagship LEAP distro.
