Scrolling text that does not fit without wrapping

[David Ventura]

Hi
I want to scroll some text on top of a video file, this works OK using
textoverlay with position=absolute and modifying the deltax attribute to
make it scroll.
If I use a really long text, it fits the width of the video and wraps to a
new line, and also scrolls OK.

My problem is that setting wrap-mode=none with really long text (that
obviously doesn't fit in one line, hence the scrolling) pango throws a fit
and does not render text

I get spammed to death with:
(python3:11404): Pango-WARNING **: pango-layout.c:3209: broken PangoLayout


My code is here: https://hastebin.com/voqebetalo.py
but the pipeline essentially is

filesrc ! decodebin name=decoder ! textoverlay ! autovideosink decoder. !
autoaudiosink
