I've just upgrade to Fedora 35 using dnf, and tried to use wayland with plasma.

Mostly it works well (with F34 plasma wayland was nearly unusable for me), but there are a couple of small problems.

I have a bash script set to run on startup, which invokes various applications and puts them in the background, and then exits. On X11 the applications keep running, on wayland they also exit. I found the fix was to add "wait" at the end of the script.

They shortcut keyboard mapping for the numeric keypad is broken, so that if I use KP_UP on the numeric keypad, the UP key is also mapped. I'm not sure if this is a feature or a bug. On X11 they are treated as different.

The python gtk FileChooserDialog is strange. With the code here: https://python-gtk-3-tutorial.readthedocs.io/en/latest/dialogs.html on X11 the buttons are shown in the expected colours at the bottom. On wayland they are darkĀ  on black and shown at the top.

Regards,
Chris
