It seems like the two options : "autoopen & autoclick recaptcha"
are detected by recaptcha v2 over a long period of time, and after a time will increase the demands for captchas (e.g. you'll get 4 or 5 verifications instead of 1)

After a cooldown of several days & disabling those options, seems like it returned to normal verifications.

EDIT: ho also, unrelated to the above but the window in Jdownloader that opens with those options, refuses to close in case I want to cancel/close it without doing the captcha or if the captcha failed for some reason.
