OBS is doesn't work when I have it as a game capture because it needs to be on the top of my main monitor for it to show up. but if i minimize it, the PNGtuber wont show anymore. Also when i click anything on my main monitor it doesn't work because its on top.

Yes, I am using the steam version

it can't be minimized because it won't be rendered in the background. you can just put it behind obs or something, just don't have it on top
