I used KDE (24.04) for a while now. Also used Linux 2000-2008-ish. Have read APUE.
When I win-left/right a window and then resize it, then close it, now win-left/right always resizes it as previous one. There’s no way to reset it to 50:50 (unless logout).
Notification center is obnoxious. Regular “Program stopped working” with zero details. Why do I need this information. Copying a folder in dolphin pops up a progress notification that doesn’t go away when finished. You did something, expect a notification to pop up. You did nothing, still expect it.
Windows either steal focus or fail to steal it when needed, depending on your settings and astrology. Software update nags you to click update, then you click it, then it downloads something for a few minutes (you go doing your things), then a sudo password popup fails to get focus, and it all crashes after a timeout. Or things will pop up right in your face. VNC connection closed? Yes, bring that white empty window to front asap and tell “Connection closed” with an OK button.
Start menu was designed by an idiot, a wrong mousemove and you are in a wrong section. Sections reside exactly on the 80% of bezier paths from start menu to the section content and have zero activation timeout. So you have to maze your mouse around to avoid surprises. Logout, restart, shutdown, sleep buttons in the start menu all show the same fullscreen “dialog” that requires you to choose an action again. What’s the point of separate buttons even.
I could go on about non-working automatic vpn connections, mangled fonts/dpi/geometry if you vnc into a turned off physical display, console that loves printing ~[[A half of the times when you press an arrow. And so on and so forth, the list is so big I just can’t remember it.
Idk how Linux users are using Linux so that they do not meet any issues.
