hmmm, well the alpha completely breaks the function of all my textboxes...is there a way to implement it in myself?
I'm not sure. I would take a look at the PR linked in the issue and see if you can convert the code into GDScript.
You could also try taking the code in the PR, download the Godot 3.0 repository, apply the changes from the PR into the Godot 3.0 code, and see if it compiles there.
I suppose another way would be going through all of the text in the TextEdit every so often and adding \n to lines over a certain length. I am not sure how feasible or useful that would be, but other than that I really have no idea.
