AHH this message is so old, I’m so sorry ;___; but thank you so much for your lovely message! ❤

I’m afraid I’m not the best person to ask, though, because I use Fraps and it (usually) works just fine for me. D: I’ve heard of some people using Gadwin as an alternative though, it might be worth a look? I’m sorry again! Hopefully you were able to figure something out in the eternity it took me to answer your question~ ❤
EDIT: We have a suggestion for Bandicam! Thanks @rowenalupin 😀
