1/2 screen goes blank during meeting I attend when host shares

Hi @mickenduraplas! Welcome to the Zoom Community. Is the content the host sharing being blacked out? 

I'd be happy to help you figure out what's going on 🙂

Thanks

When in a meeting I can see all participants but when host shares then 1/2 of the screen goes black and I cannot see what is shared on their screen through blacked out section
