TL;DR: too many settings/options, bad defaults, missing some actually useful ones. I always go back to XFCE or MATE. Edit: fixed some typos.

KDE has a bad reputation because people had bad experiences with Kubuntu. Gnome 2/MATE is old, slow, and bloated, but it's what people are used to. Unity is total crap, but it's the only Linux experience many users have had. Nor did KDE get much of a reputation with the lightweight crowd because of XFCE and LXDE.

2022年4月11日 · My experience after a day is that KDE/Plasma: has applications crashing a lot, without much details about why, but asking me to send a bug report. Browsing and SMB share always crashed instantly. The applications were kind of annoying too: When I've wanted to change the shell of KConsole (set to zsh when my /etc/passwd shell is bash), it refused.

广义的KDE 是由 Plasma桌面环境、库、框架 (KDE Frameworks)、和应用（KDE Applications）组成的软件项目。 优点. kde 是一个功能齐全的桌面环境，窗口管理器kwin很强大，特效巨多，plasma shell 有各种官方自带的小部件加持能满足各种需求。

2024年5月13日 · Make sure to check your panel options and ‘effects’ like blur. You could try creating a new user and comparing the appearance. Yes, the desktop did reset but the panel stuff still looks bad, with no spacings, wrong alignments, and so on.

2013年9月10日 · The current version of KDE is KDE 4.11, I would recommend updating. Please also note that the defaults can be easily changed, with other Plasma themes, colour schemes and other customisations being available to change the appearance of KDE.

2023年9月23日 · Most people thus won’t bother, and therefore will assume that “Linux is bad” if the default desktop experience appears broken. Another notable example is the default lack of an “up arrow” in Dolphin.

2024年6月29日 · Plasma 6 update is disappointing. More bugs than Plasma 5, at the time of writing I have already filed 3 reports about the task switcher, 1 about the panel, and some others. Minutes ago I filed one about fullscreen crashes. And among them some are about performance issues. Things that were smooth in Plasma 5 is now sluggish and glitchy in Plasma 6.
