I know this has been a thing since like forever, and I have no idea why the blur() function is so resource intensive, but I was wondering if it could be fixed somehow. Modern websites using the blur function tend to become incredibly unresponsive over a short period of time, and this has been especially the case with the introduction of YouTube's ambient mode (enabled by default on dark theme) which causes Safari and Orion to lag incredibly. I know that blur filters are resource heavy but the penalty on Safari is just ridiculous.
