One program that comes to mind is Protonmail Bridge. I first tried installing the RPM via Discover, and it silently failed every time. Next, installed it from the terminal and got an error about missing DejaVu fonts--no problem, I'll just install them from here, but unfortunately I was getting the same error. I tried to "install anyway" ignoring dependencies--failed again!

Another issue trying to install the linux-surface kernel. The GUI package failed to install (again, silently), and command line packages kept failing since the linux-surface kernel was on 6.6.6 and the rolling release kernel was on 6.6.7--eventually I chrooted in from a live USB, removed the kernel, and replaced it with the linux-surface kernel, but the fact that it kept failing with a "success" message was confusing! Then I had to compile iptsd--on Arch I'd 'pacman -S git meson ninja gcc etc.', and searching and selecting package groups via YAST (and hoping my compilation worked) just felt clunky.

I did manage to get everything up and running eventually (save Protonmail), but at that point I'd messed up my installation to the point where I had to start over, and I just loaded up EndeavourOS instead.

I'm sure a lot of these issues stem from a lack of understanding of Tumbleweed itself, and when I get another desktop I'll be happy to try again. I did love the setup process though--super polished KDE Plasma, and everything that was possible with the stock kernel (even autorotate!) worked out of the box!
