I generally only use Linux for programming just because how convenient and straightforward it is, but beyond that I have no incentive to move.
I like KDE but the ui is jank af right now, after logging in, it takes a solid 1-2 min for the taskbar to actually popup, and opening file manager including any file dialogs takes about 5-10 secs which is pretty insane since I'm running on a pretty powerful PC with a Samsung 990 pro M.2.
For context I am using Endeavour distro with nothing else modified.
Yea no shit I have to figure out why it's having issues, but my point is that I still have to jump through hoops just to figure out what's wrong, I have a life to deal with besides being on my pc for hours on end
If you don't have time to tinker maybe consider another distribution more suited to your needs. Waiting 5s for every action is not a time effective solution.
