So what? For newbies it isn’t as bad rant Youtubers tend to claim, but yeah I guess the problems are real. However, my brother has daily driven Manjaro KDE for 4 years and hasn’t have bigger or more issues what you would have with Ubuntu.
I also recommended to try it out, not to daily drive it. Manjaro’s Sway configuration is much more fine-tuned than in the Fedora Sway.
