Issues like these on Wayland cannot be addressed by KaOS, these are upstream. As mentioned often, Wayland is for a good reason not default here. Certain graphics drivers complete unsupported, input issues, Plasma still showing many more bugs than in X are some of the well documented reasons.
KaOS will keep following upstream progress for Wayland and release a Wayland based ISO every now and then, but if you need certain functionality missing in Wayland but present in X, make sure to just use X.
