WebSight SopText does not work


I am trying to write some text on a video using the websight backend, but it seems that is not working fine…

Basically, the code is the following:

show("boxes", [&](isaac::sight::Sop& sop) {

const std::string text = "my text";
sop.style = isaac::sight::SopStyle{"green"};
sop.add(isaac::sight::SopText(text.c_str(), isaac::Vector2d(10.0, 10.0)));


I am able to draw a rectangle or a circle, but the text is not been shown. Is there a bug in the SopText function or am I doing something wrong?

Thanks in advance!
