Mouse scrolling horrible

Something changed at the wiki and the mouse scrolling experience is horrible on my side. It is like each full mouse scroll down it scrolls randomly a few tick and stops. Something to do with the menu it seems to stop at each title in the page. On long page I have to use the scroll bar by clicking it or else I can’t navigate.

//EDIT: and sometimes the page scrolls perfectly like now I wanted to take a video and it works good I can scroll down quickly.

Which browser you use? Can you try different browser?
