What kinds of bugs are you talking about? I think part of the problem with KDE is that it's large enough that two users might be using completely different parts of it---I find that it's far more stable than GNOME, for instance. I'm not a fan of how its compositor makes scrolling look (I much prefer how Sway or even Windows does it) or how the compositor interacts with SDL applications, but that's not exactly a "bug".
