Those are rather old versions and don't have anything for proper
rendering of text over the video without going through the CPU.

They still shouldn't fail that way (and just be very slow), but that
might be a change done by the RPi people or something that is long
fixed in newer versions already. AFAIU what you're trying to do works
with the latest versions.
