Adamus i also cant use the new cv (the old one is bater ,but there was abaug that cant change the speed slider) but when i try use only the old one its not always let me do it, and as you said its give me stranges shapes always
if you use G2 G3 its much bater ,if you use curve with G1 its almost cant use
i sent here many messege ,but never get soution ,only that i told you avoid use G1 in curve shape
