Description
-----------

Good afternoon.

This is weird.

I have a text editor prog using TextEditor control and when i load the program with a file arg to pre-load text on start and ShowLineNumbers is set true the text is placed far left , overlapping the LineNumbers.

As soon as i click the editor the text jumps right a bit to where is should be.

The does not happen if the form is already opened and i load text into the editor just on program start.
using QT or GTK makes no difference.

here's a clip of the glitch.
