Is it possible your issues are down to your preferred distro packing KDE badly? The few times I’ve tried Kubuntu (for example) KDE has felt laggy. On Slackware, OpenSuse and Arch it flys though. This was true in the 3.x days too.
I’d also be interest to know what WM / DE is your usual daily driver and comparison here. Does it do compositing? If not, I wonder if the issue is graphics hardware and running KDE with software rendering would work better (though if you’re going to do that then you’re probably better off with an older DE or WM).
As an aside, I’ve been running KDE since the 1.0 and I my personal opinion KDE is the best now it has ever been.
I went to Gnome for a while but never felt at home there, too many weird (to me) ux decisions. I finally settled on Xfce and it works great. Nothing fancy, it just does its job.
I’ve not used XFCE in 10 or 15 years but I always had a good experience when I did need it. In fact I preferred that over GNOME too. Completely just my personal preference, though the leaner footprint was a big incentive.
Thanks for sharing your thoughts. All this stuff basically boils down to personal preferences at the end of the day, but it’s often interesting hearing what peoples preferences are.
I agree, every person has a different set of preferences and priorities. For me it just has to work reliably and not get in my way, and design is less important. But I still try to make my desktops look good.
iOS certainly would have helped fuel the change too but you could see this trend in desktop UX even before the first iPhone was announced.
My comparison is Windows because after KDE 3.5 was dropped from ArchLinux I was just too fed up with all the issues at the time. Around that same time they also started messing with the sound subsystem (switching to PulsAudio) and I couldn't even play mp3's without stuttering under load (this worked fine before). I just needed something that worked and it's been like that ever since, I don't have the motivation anymore to get under the hood and fix things, I just want my computer to work.
"The TDE project began as a continuation of the K Desktop Environment (KDE) version 3.... Trinity is an independent fork..." (from the "About" page)
Kwin is generally great though, and many of the KDE applications are top-tier.
There's a project called Trinity, which is essentially KDE 3.
