Are you sure it is not just chrome? Chrome is a large resource hog and takes up logs of memory often so it may not be a bug. Also I don’t seem to be able to replicate your issue on my laptop and I use crome.
Don’t think this should effect this cuz you said about it being only on 3D models but do you have a large amount of tabs or something open?
No it is not from chrome, as soon as I enable the 3D view, the CPU usage starts going up and it lags my computer. It works perfectly fine though in 2D view mode.
This seems to be a hit or miss, some people that I had test it had the same issue while others didn’t so I am not sure what’s happening.
Are you using any Roblox web extensions by any chance, such as RoPro or R+? I’ve noticed this exact problem occurring when I have RoPro enabled & I flip on any 3D views on the site. Disabling ropro stops the issue.
