I love KDE since KDE 3.5 but after KDE 4 its been weirdly unstable. Even now, I use KDE daily on Endeavour (Arch) and it will randomly kill the taskbar etc and restart itself, which is cool that it can self-clean but why does it fail like that randomly? I hate it because other DEs feel unstable or like the UX is worse. KDE has the exact UX I like, but I do hate the one thing browsers / KDE does where my clipboard is hijacked if I highlight text, not sure if I mistakenly made it like that or what but it drives me up a wall, sometimes I want to highlight text to paste over.
Bad compilation options, and/or bad driver/firmware interactions.
I'm using it on CachyOS with on old intels(Kaby Lake Core i5-7500t/Core i7-7700t) with old intel integrated graphics(HD630), and it never did that. Since early Plasma6/late Plasma5 times. Cant recall exactly anymore, for about 2 years now. In fact, since Plasma6 it reminded me of the good old KDE3 days, again. Except for the memory usage maybe. OTOH the systems have much more memory since the times of KDE3, so shrug?
KDE lost some corporate support when SUSE changed their default to GNOME in about 2005(?). I think it sees some use in the automotive world but aside from that it's all volunteer work.
I missed KDE 3.5 for many many years, as KDE 4 was terrible by comparison, and went to MATE due to the awful GNOME 3. KDE 3.5 was so so usable and Konqueror handled everything well.
KDE 4.0 - which introduced plasma - was released in 2006, and it was awful and wasn't supposed to be generally available (blame the distros and/or poor version naming). By version 4.5 (2010), KDE had stabilized. By the time Gnome 3 and Windows 8 were released in 2011/2012 respectively, KDE plasma was pleasant to use and rock-solid
It felt great to watch Gnome stumble after all the shit-talking, some schadenfreude was in order. I didn't care much for Windows 8; Vista was a the bigger mess of a release.
