Anybody has an idea how to that?

Just draw a separate black rectangle (with jit.gl.videoplane or mesh, etc.)

yes, it's what I want to do, but the text will change, probably quickly, I can't place and size the rectangle manually, I need to have it automatically "follow" the text

Indeed, it's intriguing that [jit.gl.text]'s "boundcalc" attribute is undocumented.

In any case, you'll have to draw the rectangle yourself, it's not going to be drawn by jit.gl.text.

As a first step, you could resize the rectangle when your text changes, using an approximate length computed from the number of characters in your text (even a precise length if you were to use a monospaced font).

jit.gl.text3d does answer to "getbounds" and I can use this to draw a rectangle.

I found a solution.

Interestingly, it works even though "boundcalc" is 0.

Yep, it looks like you need [del 10] to get the most recent bound values ([deferlow] works as well on my machine).

Nice, indeed.
