Took some time to find the switch but I succeeded in starting an Xorg based
session. I've been using it for the whole day today without a single
repetition. There are also no libinput error messages in system log.

If you have more debugging suggestions, I'l be happy to perform the data
collection.

Thanks, Michal, for looking into it. On my side the issue appears in waves.
Mostly there are no problems and only occasionally the system becomes sluggish
and the key repeat trouble triggers. Looks like something is running in
background but I haven't yet investigated.

It is possible that also VirtualBox is using Wayland directly as it is Qt based
and has the plugin built in.
