A quickie: I switched back to Wayland but noticed that the mouse cursor appears misaligned for some apps [that is as specific as I’d like to be right now :-)]. It’s like the cursor is actually pointing a cm below where it appears on the screen. This is a known issue [1] and there is a fix:
apt remove xserver-xorg-input-libinputThat worked for me after a reboot. For posterity, the original post mentions a sequence of steps. I didn’t try them out, the version probably should be adjusted to 24.04.
apt install xserver-xorg-input-synaptics-hwe-18.04
apt install xserver-xorg-input-evdev-hwe-18.04
apt remove xserver-xorg-input-libinputReferences
