@kde I’m quite happy with the Plasma6 release, but I have number of regression with respect to Plasma5.

The worst, by far, is that lockscreen seems to be broken. I use password or fingerprint, with pam configured to ask for fingerprint after password failure. When I unlock after sleep, the greeter only displays an “unlock” button with an open lock icon. Clicking it does nothing. If I manually trigger the screen locker, I can unlock once, but on the second try it usually hangs.

Second problem: touchpad gestures in wayland. It was already a pain that one could not personalize these actions, but at least the defaults were ok for me (3 finger up/down for desktop grid/present windows). And I could use fusuma for more.
The new defaults hijacks all 3-finger gestures to scroll one virtual desktop up/down left/right which I find useless.

And all those widgets which have not been ported yet, and probably never will. I tried to give a quick look at the two I used most, but it is too far away from my kind of programming.
