--- Comment #23 from Carlos Alves <cbc.alves at gmail.com> ---
After reading everything here, if it is reproduced just after konsole opens, it
is probably not related to reflow. But I can't test it here, wayland doesn't
run here, and it is a bug related to some wayland bahavior with the input.

Luis Javier Merino seems to have tested it and solved.
