I suspect this does cause redrawing errors. Have you tried moving the
cursor up or down to cause the text to scroll?
It can perhaps be used as a hint, that copying an area is slower than
redrawing it. Hoever, this is unexpected, perhaps something in the
deleted lines was expensive. gui_gtk3_redraw() perhaps?
