No complaints about Fedora KDE specifically. I’ve had it on my spare laptop since version 30 or so. Desktop is on 41 now. The only “issues” I’ve had running this full-time is lack of support for Fidelity Active Trader Pro (which kinda sucks anyway), I haven’t been able to make my bluetooth shipping label printer work yet, and I haven’t gotten my Logi MX Keys / Master S mouse working as it works in Logi Options (on windows or mac) to switch over to my work mac as intended. Otherwise, I prefer it to other distros I’ve used.
