You might want to upgrade it with a graphics card tho, because you're limited to 75hz above 1080p, but it isn't worth it that much.

videos above 1080p can sometimes cause problems if they have heavy encoding like vp9 or av1

Yeah they're probably decoded in software because I doubt that the integrated graphics supports hardware decoding of those recentish codecs.

At that point, just put a gt1030 in it.

Have you tried hyprland with animations on?

Yeah... I wonder if it's a specific desktop environment. although I thought people generally considered gnome on the slow side but that's what my pi runs pretty decently
