Have you tried Xfce? Usually it's pretty damn stable and bug-free in my experience (outside of one time I found a bug which had a perfect workaround anyway) in my past 7 years of using it.
Nah, I wanna hear about bugs that have affected you that you can confirm are bugs :-)
I'm glad you asked. 5 seconds ago gnome froze and sent me back into the login screen and closed all the apps I had open. Ask me again in 20 seconds and I'm sure I'll have a different bug for ya.
To be fair Windows had something like one bug per line of code in the mid 2010s. But there isn't the transparency of a public bugtracker. And good luck shouting into the void if you ever find one.
