The latest from Nate Graham:
“KDE software has historically been accused of being resource-intensive, ugly, and buggy. Over the years we’ve largely resolved the first two, but the issue of bugginess persists. Have you ever had that experience where you’re introducing someone to a KDE Plasma system and to your horror, they run into multiple bugs within moments? These are the issues we need to fix first: those that can be easily encountered within 15 minutes of basic usage.”

Sounds like a good idea - I am one of those that keeps running into such things when I try it (now getting to be widely spaced attempts). Too much complexity can be a BEAR to track down! I’ll stick with something simple for now, like XFCE with compiz… 
I love these initiatives, and I’m sure KDE will be even better after this!
I’m just going through the list, and I’ve never encountered a single bug on it, through several years of using Plasma. 
I don’t even know how to intentionally reproduce any of these bugs.
I’ve managed to reproduce one! Woot! 
This one:

But who drags the scrollbars to scroll in the current year? Maybe in 1995 I would have noticed and be slightly amused by this bug (I wouldn’t have been bothered, since no functionality is broken), but since that time mice have evolved a scroll wheel…
If stuff like this is on the priority list of bugs to fix, I presume they can’t find anything more serious, and then it’s simply unfair and incredibly nitpicky to call Plasma “buggy”.
For me it’s still the flickering when screen sharing on zoom. Something to do with renderer or desktop effects that don’t bode well with that program.
If that would work I would probably use plasma. The renderer has been an issue in the past, but most bugs, window tearing etc seem to have been fixed in the last couple of years.
I can’t comment on that because I don’t use Zoom (it’s 𝖆𝖇𝖘𝖔𝖑𝖚𝖙𝖊𝖑𝖞 𝖕𝖗𝖔𝖕𝖗𝖎𝖊𝖙𝖆𝖗𝖞). I don’t have such issue on Jitsi or when recording my screen with OBS or ffmpeg. I did have a similar problem when I was using a NoVidea GPU, though.
It’s annoying but used at work. Wish we would switch to Jitsi.
If your employer demands that you use proprietary software, they should provide you with a laptop to run it on (otherwise, they are expropriating your personal computer). But that’s just my opinion, and off topic…
I use 100% Linux, but there are hiccups here and there when collaborating with the outside proprietary world users. Hopefully it will get fixed. No issues on xfce.
I must be one of the lucky ones too. Can’t recall the last time I had a problem of any significance, at least nothing more than any other DE. My experience with plasma on Endeavour has been far better than on other distros including neon.
The only real issue I ever have is with me second monitor. When I disconnect it I adjust always have to kill and restart plasma. But that’s really the only bug I have and it’s very easy to fix now that I know how.
Given that Linux has issues with scroll wheel acceleration, dragging the scrollbar is sometimes faster.
alway there keyboard 
less mouse/trackpad the better 
EDit . 
mistake it plasma you talk about
