Try messing with the hardware acceleration options in the advanced settings. I can’t say I’ve seen any stuttering using just Intel integrated graphics or on my laptop with Intel + Nvidia quadro. If your using Linux there’s a good chance it’s a Nvidia driver issue. You could open the developer tools side by side with Firefox and Chrome and go to the network or performance tabs and compare side by side.
Honestly, same. Between the algorithm throwing wild but entertaining YouTube shorts and me starting to watch longer more educational content, I find myself going on the reddit mobile site very rarely.
