Solved in 29.0.1

Glad to hear and thanks for reporting back @Aveyron-RetD ❤️

I'm also on NC 29.0.1 and for me the issue is only partly fixed. Those blue lines still appear (not sure what the meaning of this marking is) and adding or removing text by typing seems to work again.
But pasting text still does not work as expected (text is placed at different places) and the cursor jumps around.

@Aveyron-RetD Could you double check whether pasting text does work while the lines are marked blue?

@mejo- Should I create a new issue or would it be better to reopen this one?
