Is there no way to detect a zoom-out and perhaps, after a short timeout, refresh the CAPTCHA?

hmm, detecting zoom-out, I'm not sure. Possibly a mismatch between viewport size and window size.
Refreshing the CAPTCHA wouldn't help, making it bigger to compensate for the zooming - perhaps - but seems dodgy as rounding errors could cause a lot of problems.

Maybe though there is a solution, have a zoom in button that displays it much bigger in an overlay. That could be genuinely nice in general.

I agree. I think the CAPTCHA size as it is now is too small, even for me. Perhaps we should also increase its size a bit on the field?

Did the best I could. Non-CSS / iframe CAPTCHAs will open as an overlay. Otherwise it must open in a new window because of the iframe. The larger version of the CAPTCHA will display at 4x the size.
