Works perfect, except on Youtube. I have a good gpu but when colors are inverted, Youtube videos lag heavily. Have to turn it off for youtube, everywhere else it works fine. CPU usage also goes to crazy 30% because of youtube on invert. Please fix.

Edit - Contacted the developer, gave me an extremely helpful reply. Will be resolved soon hopefully.

Dynamic Theme mode has been published. It will require some CPU on initial page loading, because YouTube heavily uses CSS variables. Also try using built-in YouTube dark theme.
